I've thought about renaming git-commit to git-commit.cmd and add this
preamble:

@echo off
rem () { :; } ; : \
sh %0 %1 %2 %3 %4 %5 %6 %7 %8 %9
rem ; : \
exit /B %ERRORLEVEL%


in place of the usual "#!/bin/sh". It requires you to have a command
named @echo.exe in the path that is a noop. Also, it is limited to 9
command line arguments.

What a hack! (*)

(*) Here's how it works:
- cmd.exe will ignore all but the sh and exit lines, effectively
invoking the script under bash and exiting with bash's exit code.
- Bash will execute @echo, define a function named rem, ignore the sh
and exit lines because they are continuations of the : noop on the
previous line. It will also run the second rem, but it is a noop, too.
