It's not for the sake of one project.  Installing Git as I indicated
is the only sensible thing for _any_ project.  For some reason, Git
for Windows doesn't have that as default; moreover, in the past I
remember some people arguing with me that what I suggest is actually
wrong (I disagree with their arguments).

I would encourage you to report this to the msysGit project as a bug.

The setting is on ~/.gitconfig and can be overridden by the
project-local .git/config file, if you need.  But my recommendation is
to switch all your Git-based projects to this default.  Otherwise, if
the project has files that need special EOL format, you will get in
trouble.

It's possible, yes.  Just make sure you have neither autocrlf nor eol
settings in your .git/config file, in the [core] section.

Once again, using anything else in other projects is just waiting for
trouble, so I really recommend this as a global setting.
