If we want to improve performance during completion on remote volumes,
it is IMO better to temporarily disable w32-get-true-file-attributes
inside file_name_completion_stat, a subroutine of file_name_completion,
since the only attribute the latter cares about is the directory bit.
The DJGPP (a.k.a. MSDOS) port does something similar there.

In fact, we could call `access' there instead of `stat', which is much
cheaper that `stat' on Windows.  Would it hurt other platforms if
file_name_completion_stat called `access', btw?
