Interesting hint, thanks. I'll probably try playing with that trick.

We already have util.fspath, which uses the also mentioned os.listdir trick.

As a side note, on Windows, there are differences between stat-ing files
and directories. For example, we have a mercurial.win32.samefile()
function, which is specified to work only for file paths - not directories.

BTW, we shouldn't reintroduce depending on win32api, but it shouldn't be
a problem to call the Windows API directly via Python's ctypes (see
mercurial/win32.py).

At the moment, I'm really tempted to kill util.samestat(). That function
can't be implemented on Windows. So basically there can't be such a
thing as util.samestat().
