This fixes Savannah bug #46715 ("testsuite error with perl 5.22,
gnulib outdated").
* doc/regexprops.texi: Regenerate this file from gnulib's changed
regular expression dialect definitions regex.h.  The effect is for
regex types egrep and posix-egrep to become synonyms.
* NEWS: Mention this change.

into line with GNU grep (see
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=20974#22).
