Drew,
I went back and tried using your grep+.el library.
I have a couple of questions:
1. Is it possible to tweak it so it would remove/toggle comments in the grep
window for a C language based file or assembly?
2. Is there an option to highlight the match in the grep window? "this is
different than my question asked in this thread." I am really looking to
highlight each match in a busy grep window.
