[PATCH] git-sh-setup: work around Cygwin path handling gotchas

On Cygwin, tools built for Cygwin can take both Windows-style paths
(e.g. C:/dir/file.txt or C:\dir\file.txt) and Cygwin-style paths
(e.g. /cygdrive/c/dir/file.txt), but Windows-native tools can only take
Windows-style paths.  Because the paths that are relative to $GIT_DIR,
e.g. the name of the insn sheet file of the "rebase -i" command, are given
to the programs with $GIT_DIR prefixed, and $GIT_DIR in turn is computed
by calling "pwd", wrap "pwd" to call "cygpath -m" to give a Windows-style
path, in a way similar to how mingw does this.
