Subject: bug#6808: 24.0.50; Incomplete match highlighting with `query-replace-regexp'

From: Tassilo Horn <[email-masked]>
Date: Fri, 06 Aug 2010 08:46:07 +0200

The matches to be replaced by `query-replace-regexp' aren't highlighted
completely, although the replacement is correct.

Here's a recipe:

1. emacs -Q
2. Create a buffer with contents:

 #1 153030 120 = 423988
 #2 152845 181 = 1500234
 #3 155160 247 = 767821
 #4 155160 310 = 11131347
 #5 155160 319 = 13979167

3. M-x query-replace-regexp RET [0-9]+ = RET RET

Result:

- The first match "120 =" is highlighted completely.
- All further matches have only the last number highlighted, e.g. "1 =",
  "7 =", ...
- Performing the replacement replaces the correct, complete match,
  e.g. "120 =", "181 =", "247 ="

`re-builder' doesn't have this issue.  It highlights the complete
matches.
