[Bug regex/1232] New: regex.h comment for RE_NO_EMPTY_RANGES is incorrect

["eggert at gnu dot org" <sourceware-bugzilla at sources dot redhat dot com>]

James Youngman reported that the comment in regex.h is incorrect
for RE_NO_EMPTY_RANGES: when "ending range point collates higher than the
starting range point", the range is a normal range; it is not ignored.

Also, the comment isn't clear about what it means for a range to
be "ignored".

I'll attach a patch.
