Good job.

Ugh. Ok. So it appears that whatever Windows posix emulation library
we use is pretty broken.  Looking at the "p_stat()" implementation in
libgit2, it just does a utf8->wchar expansion.

We actually do the same thing in "subsurface_open()", for all the same
reasons. I wonder why the system "stat()" routine can't just get that
right? What the hell is wrong with Windows libraries? Why doesn't the
windows "stat()" routine just DTRT?

I think this is the right thing to do, we already end up having all
the pieces, and we already use "fstat()" even on windows, so we could
just do a subsurface_stat() exactly like we do subsurface_open().
