terse: pconvert() entries added to the temporary terse dict for Windows

Recent additional testing revealed this problem on Windows:

AFAICT, the status list (input and output here) is always in '/' format.  The
'\' printed output on Windows is because each file is run through repo.pathto()
-> dirstate.pathto() -> util.pathto().  (And that function states that the
argument uses '/' separators.)

I fixed a similar issue in 362096cfdb1f, and given the apparent need for these
strings to be in '/' format, I wonder if cmdutil.dirnode() should be rewritten
to avoid os.path.join().  But it looks like all entries added to the temporary
terse dict should use '/' now, and cmdutil.tersedir() looks like the only user.
