Process backslashes in regexprep replacement strings in Matlab compatible fashion (bug #45407).
* NEWS: Announce change. Backslashed escaped ordinary characters are now
replaced by the character itself with no emitted warning.
* regexp.cc (do_regexp_rep_string_escapes): Change default case statement to
silently convert unrecognized escaped character to the bare character itself.
Pass the special sequences of '$' and '\' through since these must be handled
by lo-regexp.cc.
* regexp.cc (Fregexprep): Add BIST tests for new behavior.
