[PATCH 2/2] On Cygwin support both UNIX and DOS style path-names

[Pascal Obry <pascal@obry.net>]

In fact Cygwin supports both, so make Git agree with this.
The failing case is when a file is committed in a sub-dir of the
repository using a log message from a file specified with a DOS
style path-name. To reproduce:

   $ cd src
   $ git commit -F c:\tmp\log.txt file.c
   fatal: could not read log file 'src/c:\tmp\log.txt': No such file \
   or directory.
