[PATCH v2] Fix safe_create_leading_directories() for Windows

[Sebastian Schuberth <sschuberth@gmail.com>]

When cloning to a directory "C:\foo\bar" from Windows' cmd.exe where "foo"
does not exist yet, Git would throw an error like

fatal: could not create work tree dir 'c:\foo\bar'.: No such file or directory

Fix this by not hard-coding a platform specific directory separator into
safe_create_leading_directories().
