Do not alter match data in Fcapitalize etc.
Without this patch, (capitalize "x") can alter the match data,
which is not what users expect. Problem found by running
morse-tests-unnato-region in a stripped-down Emacs.
Perhaps ‘load’ should also save and restore the match data?
That would be a simpler fix, though arguably incompatible.
* src/lread.c (save_match_data_load): New function.
* src/chartab.c (uniprop_table):
* src/doc.c (reread_doc_file):
* src/eval.c (Fautoload_do_load):
* src/fns.c (Frequire): Use it.
