1) with DH=0 (default) it returns name run together without '.' and
without any spaces as are present in W9x versions.  Pretty useless.
2) with DH=1 (better) it returns name with '.' in place (so we must
get rid of our post-processing code). BUT...

In both cases, any special characters such as _ or ! put garbage into
the file name stream:
_.CVS -> _67C0.CVS
!.cvs -> !60D2.CVS

None of the flags in DL seem to make any difference.  So it appears we
either force fncase=y all the time by returning a bogus string, or 
do something a little better than nothing.  Just truncating the 
string to 8.3 and upcasing does fix 99% of the examples on the disk.
