This commit introduces a new option "--[no-]stripspace" to git notes
append, git notes edit, and git notes add. This option allows users to
control whether the note message need to stripped out.
For the consideration of backward compatibility, let's look at the
behavior about "stripspace" in "git notes" command:
1. "Edit Message" case: using the default editor to edit the note
message.
In "edit" case, the edited message will always be stripped out, the
implementation which can be found in the "prepare_note_data()". In
addition, the "-c" option supports to reuse an existing blob as a
note message, then open the editor to make a further edition on it,
the edited message will be stripped.
This commit doesn't change the default behavior of "edit" case by
using an enum "notes_stripspace", only when "--no-stripspace" option
is specified, the note message will not be stripped out. If you do
not specify the option or you specify "--stripspace", clearly, the
note message will be stripped out.
2. "Assign Message" case: using the "-m"/"-F"/"-C" option to specify the
note message.
In "assign" case, when specify message by "-m" or "-F", the message
will be stripped out by default, but when specify message by "-C",
the message will be copied verbatim, in other word, the message will
not be stripped out. One more thing need to note is "the order of
the options matter", that is, if you specify "-C" before "-m" or
"-F", the reused message by "-C" will be stripped out together,
because everytime concat "-m" or "-F" message, the concated message
will be stripped together. Oppositely, if you specify "-m" or "-F"
before "-C", the reused message by "-C" will not be stripped out.
This commit doesn't change the default behavior of "assign" case by
extending the "stripspace" field in "struct note_msg", so we can
distinguish the different behavior of "-m"/"-F" and "-C" options
when we need to parse and concat the message.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
