Patch to allow trailing dots on managed mounts

[Mark Paulus <mark dot paulus at mci dot com>]

This patch is as trivial as I could get to allow trailing
dots to be used on a managed file system.

Unfortunately, my company will not sign the waiver,
so I cannot sign up for any significant changes to
the cygwin sources.  So, hopefully, this patch is
small enough to squeek under the limit, or it can be a
starting point for discussions on how to fix the original
problem.

    * path.cc (path_conv::check):  retain trailing dots and 
      spaces for managed mounts.
