Provide a "get_dirname()" routine, that takes a pathname and returns

either a pointer to the directory part of the pathname (after stomping
on the pathname separator with a '\0', so don't use this on pathnames
you plan to use afterwards), or NULL if the pathname contains no
directory part, and make it handle Win32 pathnames on Win32 systems.

Use it to get the containing directory of the currently open file, so
that the "chdir()" stuff we do to cause the "File:Open" dialog box to
show you files in the directory in which you last looked works on Win32
systems.
