Re: Character classes -- what about them -- need to support them?

What do you mean by "support in regexps but not in
re-search-forward"? AFAIK we have no support for them at all,
certainly not at the C level.
I'm probably just confused by a comment in regex.h which says ...
/* If this bit is set, then character classes are supported. They are:
[:alpha:], [:upper:], [:lower:], [:digit:], [:alnum:], [:xdigit:],
[:space:], [:print:], [:punct:], [:graph:], and [:cntrl:].
If not set, then character classes are not supported. */
#define RE_CHAR_CLASSES (RE_BK_PLUS_QM << 1)
...
and line 2033 in regex.c which reads:
#define IS_CHAR_CLASS(string) \
(STREQ (string, "alpha") || STREQ (string, "upper") \
|| STREQ (string, "lower") || STREQ (string, "digit") \
|| STREQ (string, "alnum") || STREQ (string, "xdigit") \
|| STREQ (string, "space") || STREQ (string, "print") \
|| STREQ (string, "punct") || STREQ (string, "graph") \
|| STREQ (string, "cntrl") || STREQ (string, "blank"))
They made me believe we had some support for it.
