GCommit doesn't work with fugitive.vim under windows xp?

I开发者_Python百科've just discovered fugitive.vim, which is pretty cool. However, I've run into a problem (this is using windows xp, msys git 1.7, fugitive.vim 1.1, and gvim 7.2). Adding files to the index and checking the status works just fine, but when I do a :GCommit, a command prompt flashes for a second and nothing happens. No way to type a commit message and nothing is committed. Is this a bug? Am I doing something wrong?

It looks like issue 428 of msysgit.
(From issue 467)

Reported by michaelrgeddes, Apr 07, 2010

What steps will reproduce the problem?
From cmd shell

set GIT_EDITOR=false
set ERRORLEVEL=
git commit
if errorlevel 1 echo Has an error %ERRORLEVEL%

Expect to see "Has an error 1" but don't.

git version 1.7.0.2.msysgit.0 running on Vista.

Important since it causes :Gcommit failure in 'fugitive' vim integration.

Solution: patch the cmd/git.cmd script of your current msysgit installation.

Here is an possible situation that can cause the problem, which I experienced. I list it here in case it can help any one else that met with the same issue.

It happened that after I installed git (downloaed from http://git-scm.com/), I didn't set the git global config user.email. After I setup that via command line, Gcommit works. So if some one met with the same issue, please make sure that you can commit from command line, and then try Gcommit.
