This report is about GNU emacs 20.7.1 on NT 4 (SP 4 and 5).
The documentation for regexp i-search says
If you type <SPC> in incremental regexp search, it matches any
sequence of whitespace characters, including newlines. If you want to
match just a space, type `C-q <SPC>'.
I find that newlines are included in some regexp i-searches are not in
others. For example, if I have a file with
and I type "<C-M-s> test<space>ph" I get a failing regexp i-search.
If I type "<C-M-s> test[ \t\n\r]+ph" I get a failing regexp i-search.
The value of search-whitespace-regexp is set to "\\s-+".
Workaround: Regexp-isearch works correctly if I include the following in
'(search-whitespace-regexp "[ \t\n\r]+"))
Based on responses on gnu.emacs.help, the problem may be related to the
different definitions of newlines in dos and unix. I don't think unix users
have this problem.
