Git does not understand absolute Win'dos' path

Hi

Maven's release plugin prepares a call Git like in this example:

cmd.exe /X /C "git commit --verbose -F C:\cygwin\tmp\maven-scm-915771020.commit pom.xml"

Git doesn't seem to understand the -F argument and treats it like a relative path (relative to the repository root):

$ cmd.exe /X /C "git commit --verbose -F C:\cygwin\tmp\commit pom.xml" fatal: could not read log file 'mytestdir/C:\cygwin\tmp\commit': No such file or directory
