[bug-gnulib] ME_DUMMY in mountlist.h should probably recognise "subfs".

[James Youngman]

Dmitry V. Levin tells me that the "subfs" filesystem is like autofs
and should therefore cause ME_DUMMY in mountlist.h to result in a
nonzero value.

He has submitted a small patch against findutils to such an effect,
but one of the files it patches if gnulib's "mountlist.h" which is
part of gnulib and hence isn't in findutils' CVS repository.

The patch and associated descriptive text is at
http://savannah.gnu.org/patch/index.php?func=detailitem&item_id=3703

Please consider applying the appropriate part of the patch to gnulib.

Thanks,
James.
