bug#814: 23.0.60; Fold case error in isearch / highlight-regexp

[Lennart Borgman (gmail)]

If I start isearch and grab a word

  C-s C-w

and highlight this with

  M-s o h r

then if the word contains upper case letters there will be no highlight.

This is on w32 with a fresh checkout, but using my patched version of
Emacs (which I hope does not matter here).

In GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600)
 of 2008-08-28 (patched)
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (3.4) --cflags -Ic:/g/include'

bug#814: marked as done (23.0.60; Fold case error in isearch / highlight-regexp)

I've checked in a fix.

(It doesn't handle case-fold behavior for regexp search.  That feature
is rather non-trivial to implement.)

I don't understand this recipe.  For instance, from the NEWS buffer,
`C-s C-w' grabs `GNU' into isearch, and `M-s o' displays a window
showing occurrences of that word in the buffer.  What is `h r' for?

Please provide a recipe recipe, thanks.

Uhm, did not Jurij implement that? Oh, eh sorry:

  M-s h r

for highlighting a regexp directly from isearch.
