There are a couple of things here. The short answer is that

editor = C:\WINNT\gvim.bat -f

Should work for you.

So should:

editor = c:/winnt/gvim.bat -f

The issues I know of are:

1) On my machine, if I don't supply '-f', then gvim will start a
different process rather than running having the .bat wait for input. I
don't know why we interpret this as not being able to start an editor.
From what I've seen, the editor starts, and on other platforms, that
would give us "commit canceled"

2) You can't use a path with spaces. So you can't use "C:\Program
Files\Vim\7.0\gvim.exe". This is because we split on whitespace to allow
you to specify arguments to pass to the command. We are discussing how
to accomodate the 2 different issues (how do we escape a space properly).

3) Double slashes are probably just confusing things.

4) I'm running on WinXP, which might be more lax about what sort of
paths it can start. I thought I did some testing and trying to spawn a
process using forward slashes and it failed. But I just tried it, and it
was working.

I think the reason it was failing is because we check the return code.
And if it is "127" (which is probably -1), then we assume the editor
didn't start. And I'm guessing gvim.bat returns exactly that.
