And the man page is already too long,
That's subjective. To me, documentation is the "right" length if I can
quickly find what I need to get the job done. I wrote the patch because
it will make grep easier for me to use, and I hope other people, too.
This is an issue all we GNU maintainers face. Keeping things up to
date in both the texinfo manual and the man page gets old after a while,
so I understand where both sides are coming from.
You just have to look at the right man page.
man 7 regex
This page defines regular expressions and in turn references:
man 3 wctype
This page then references:
"alnum" - realizes the isalnum(3) classification function
"alpha" - realizes the isalpha(3) classification function
"blank" - realizes the isblank(3) classification function
"cntrl" - realizes the iscntrl(3) classification function
"digit" - realizes the isdigit(3) classification function
"graph" - realizes the isgraph(3) classification function
"lower" - realizes the islower(3) classification function
"print" - realizes the isprint(3) classification function
"punct" - realizes the ispunct(3) classification function
"space" - realizes the isspace(3) classification function
"upper" - realizes the isupper(3) classification function
"xdigit" - realizes the isxdigit(3) classification function
which are really all the same page.
Perhaps the grep man page should just reference regex(7) in the REGULAR EXPRESSIONS
section.
