isearch-forward and isearch-forward-regexp documentation

[acd dfg]

This bug report will be sent to the Free Software
Foundation,
not to your local site managers!

Please write in English if possible, because the Emacs
maintainers
usually do not have translators to read other
languages for them.

Your bug report will be posted to the
address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


This is a documentation bug report for isearch-forward
and isearch-forward-regexp.

- Describe Key for isearch-forward (i.e. C-h k C-s)
  does not mention that RET typed immediately after
  C-s puts you in non-incremental search mode.

- Describe Key for isearch-forward-regexp (i.e. C-h k
  C-M-s) does not mention that you can search for
  exactly one space character by typing C-q SPC, but
  does mention that you can use [ ].  The Emacs (not
  Elisp) info node "19.4 Regular Expression Search"
  does the reverse: it mentions C-q SPC but not [ ].
  The two should be consistent in what they mention.

- When I wanted to find out why isearch-forward-regexp
  was matching multiple spaces when I had typed only
  one space, the first place I looked was the Emacs
  info node for regular expresion syntax, "19.5 Syntax
  of Regular Expressions", but that node says nothing
  about it.  It took me a while to think to look in
  the previous info node, "19.4 Regular Expression
  Search".

  The feature should also be mentioned in info node
  19.5.

- The variable search-whitespace-regexp is not
  mentioned in the Emacs Info docs for regular
  expressions, but is mentioned by Describe Key
  (C-h k C-M-s).



(This is with a relatively recent version of CVS emacs
on MS Windows from nqmacs.sourceforge.net, GNU Emacs
22.0.50.2.)
