With `git config get --type=color` the user asks us to parse a specific
configuration key and turn the value into an ANSI color escape sequence.
The printed string can then for example be used as part of shell scripts
to reuse the same colors as Git.
Right now though we set up the auto-pager, which means that the string
may be written to the pager instead of directly to the terminal. This
behaviour is problematic for two reasons:
- Color codes are meant for direct terminal output; writing them into
a pager does not seem like a sensible thing to do without additional
text.
- It is inconsistent with `git config --get-color`, which never uses a
pager, despite the fact that we claim `git config get --type=color`
to be a drop-in replacement in git-config(1).
Fix this by disabling the pager when outputting color sequences.

Our documentation for git-config(1) has a section where it explains how
to parse and use colors as Git would configure them. In order to get the
ANSI color escape sequence to reset the colors to normal we recommend
the following command:
$ git config get --type=color --default="reset" ""
This command is not supposed to parse any configuration keys. Instead,
it is expected to parse the "reset" default value and turn it into a
proper ANSI color escape sequence.
It was reported though [1] that this command doesn't work:
$ git config get --type=color --default="reset" ""
error: key does not contain a section:
This error was introduced in 4e51389000 (builtin/config: introduce "get"
subcommand, 2024-05-06), where we introduced the "get" subcommand to
retrieve configuration values. The preimage of that commit used `git
config --get-color "" "reset"` instead, which still works.
This use case is really quite specific to parsing colors, as it wouldn't
make sense to give git-config(1) a default value and an empty config key
only to return that default value unmodified. But with `--type=color` we
don't return the value directly; we instead parse the value into an ANSI
escape sequence.
As such, we can easily special-case this one use case:
- If the provided config key is empty;
- the user is asking for a color code; and
- the user has provided a default value,
then we call `get_color()` directly. Do so to make the documented
command work as expected.

When trying to parse an invalid color via `get_color()` we die. We're
about to introduce another caller in a subsequent commit though that has
its own error handling, so dying is a bit drastic there. Furthermore,
the only caller that we already have right now already knows to handle
errors in other branches that don't call `get_color()`.
Convert the function to instead return an error code to improve its
flexibility.

We have a couple of small style violations in t1300:
- An empty newline at the start of the test body.
- The test command is sometimes on the same line as the test name.
- The closing single-quote is sometimes on the same line as the last
command of the test.
Fix these.

There are a bunch of tests in t1300 where we write the test expectation
handed over to `test_cmp ()` outside of the test body. This does not
match our modern test style, and there isn't really a reason why this
would need to happen outside of the test bodies.
Convert those to instead do so as part of the test itself. While at it,
normalize these tests to use `<<\EOF` for those that don't use variable
expansion and `<<-EOF` for those that aren't sensitive to indentation.
Note that there are two exceptions that we leave as-is for now since
they are reused across tests.

This turns into a no-op merge, since more recent versions of Git
newer than 2.46 track do support the newer "git config" syntax.
* maint-2.45:
t: avoid git config syntax from newer releases
In a recent security release, 05e9cd64ee (config: quote values
containing CR character, 2025-05-19) added calls to `git config get`,
`git config set`, and `git config unset` which are not present on the
maint-2.43 branch.
These subcommands were added in the following commits, released in
git-2.46.0:
4e51389000 (builtin/config: introduce "get" subcommand, 2024-05-06),
00bbdde141 (builtin/config: introduce "set" subcommand, 2024-05-06),

branches.

When preparing the latest round of security fixes, we wrote release
notes in v2.43.7, and then successively merged those up through to the
various 'maint' branches.
However, the 2.49 release series is the first to have commit 1f010d6bdf
(doc: use .adoc extension for AsciiDoc files, 2025-01-20). This means
that we should have renamed the new-but-historical release notes from
*.txt to *.adoc during the merge into the 'maint-2.49' branch, but
neglected to do so.
Rename them accordingly to match the convention introduced by
1f010d6bdf. Since the release materials in question here were prepared
before v2.50.0 was tagged, the 'maint' track for that release series is
OK as is.

It is quite helpful to know what Coverity said, exactly, in case it
fails to analyze the code.

When I added the Coverity workflow in a56b6230d0b1 (ci: add a GitHub
workflow to submit Coverity scans, 2023-09-25), I merely converted an
Azure Pipeline definition that had been running successfully for ages.
In the meantime, the current Coverity documentation describes a very
different way to install the analysis tool, recommending to add the
`bin/` directory to the _end_ of `PATH` (when originally, IIRC, it was
recommended to add it to the _beginning_ of the `PATH`).
This is crucial! The reason is that the current incarnation of the
Windows variant of Coverity's analysis tools come with a _lot_ of DLL
files in their `bin/` directory, some of them interferring rather badly
with the `gcc.exe` in Git for Windows' SDK that we use to run the
Coverity build. The symptom is a cryptic error message:
make: *** [Makefile:2960: headless-git.o] Error 1
make: *** Waiting for unfinished jobs....
D:\git-sdk-64-minimal\mingw64\bin\windres.exe: preprocessing failed.
make: *** [Makefile:2679: git.res] Error 1

D:/a/git/git/cov-int/build-log.txt
The log (which the workflow is currently not configured to reveal) then
points out that the `windows.h` header cannot be found, which is _still_
not very helpful. The underlying root cause is that the `gcc.exe` in Git
for Windows' SDK determines the location of the header files via the
location of certain DLL files, and finding the "wrong" ones first on the
`PATH` misleads that logic.
Let's fix this problem by following Coverity's current recommendation
and append the `bin/` directory in which `cov-int` can be found to the
_end_ of `PATH`.
