[PATCH] isearch: lazy-highlighting of sub-exps of regexps

[Andrew Helsley]

Hi,

Attached is a patch for `isearch-mode'.  With this enhancement, the user 
can easily see examples of what the groups in their regular expressions 
capture as they type them.  Using this feedback should make it easier for 
the user to accurately build a replacement string when they invoke 
`query-replace-regexp' directly from `isearch-mode'.
