Update.

2000-04-06  Ulrich Drepper  <drepper@redhat.com>

	* locale/programs/charmap.c (charmap_new_char): Add parameter step.
	Support ..(2).. ellipsis.
	(parse_charmap): Recognize ..(2).. etc and pass step down.
	Correctly generate names for UCS4 characters.

	* locale/programs/ld-ctype.c (struct translit_ignore_t): Add step.
	(ctype_finish): We know the wide character value for <SP>,
	don't search.
	(charclass_symbolic_ellipsis): Handle ..(2).. ellipsis.
	(charclass_ucs4_ellipsis): Likewise.
	(read_translit_ignore_entry): Store ellipsis step.
	(ctype_read): Recognize ..(2).. etc and pass step down.

	* locale/programs/linereader.c (lr_token): When seeing comment
	character ignore only rest of line in sources but stop at escaped
	newline.
	Recognize ..(2).. and ....(2).....

	* locale/programs/locfile-token.h (enum token_t): Add tok_ellipsis2_2
	and tok_ellipsis4_2.
