doc: remove Emacs-specific documentation; match code * doc/regex.texi: Remove mention of both Emacs and non-Emacs syntax tables, as these are no longer supported by the code. Document the word character class (alnum + _). Add documentation for \s and \S. Replace mentions of #defining emacs with RE_NO_GNU_OPS (which takes effect in the opposite sense); merge the node “GNU Emacs Operators” into “GNU Operators”. For \` and \', refer to the “whole string” rather than the (Emacs) “buffer”.
