Subject: 26; Elisp manual: Please consider indexing each char class
Date: Mon, 13 Aug 2018 09:45:13 -0700 (PDT)

I wanted to go to the Elisp manual section that specifies char-class
[:blank:].  I tried `i blank', even with substring matching.  Not
recalling that such critters are called "character classes" I just used
`i regexp' (with substring matching) to find entry "character classes in
regexp".

So not a big problem (assuming you have substring matching).  But I
think it would be helpful to add entries such as these (which don't
require substring matching):

ascii character class, regexp
alnum character class, regexp
alpha character class, regexp
blank character class, regexp
...

(Even better would be to allow :blank: etc. and [:blank:] instead of
just blank etc., but I seem to recall that Info won't allow such entries.)
