This bug report will be sent to the Bug-GNU-Emacs mailing list and the GNU bug tracker at debbugs.gnu.org. Please check that the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgement at that address.
Please write in English if possible, as the Emacs maintainers usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe starting from `emacs -Q':
I have loaded the windows binary: emacs-24.2-bin-i386.zip 07-Oct-2012 09:26 47M I am running Windows 7 Professional Service Pack 1
I load a 10MB messages file (text) into Emacs. I position the cursor on the first line in the file. When I execute the command: M-x highlight-lines-matching-regexp and select a regexp to use, Emacs only highlights a small fraction of lines
that that match such regexp. If I then I-search for the same regexp, after several highlighted occurrences, I find more occurrences that have NOT been highlighted. For example, my messages file contains logging information regarding HEAD requests and HEAD responses. There are 5396
occurrences of "HEAD r" [ using command M-x count-matches ]. However, M-x highlight-lines-matching-regexp only highlights about the first 180 of these lines beyond the current window's view.
If I then position the cursor deeper into the file and re-run the
highlight-lines-matching-regexp command USING THE SAME HIGHLIGHT COLOR, there is no effect. However, if I use the same regexp but this time utilize a different highlight color, then Emacs will again highlight about 180 such occurrences, from the cursor point onward, in the new color.
Thanks, Dave
