Hi Tamas; thx for the suggestion. FYI - I added some different commands,
which I think might be more useful (YMMV) -
http://www.emacswiki.org/cgi-bin/wiki/grep%2b.el.

New, in grep mode:

`+' - create a new grep buffer (`new-grep-buffer')
`b' - choose (switch to) another grep buffer, with completion
(`choose-grep-buffer')

As before, in grep mode:
`g' - run `grep'
`n' - `next-error-no-select'
`p' - `previous-error-no-select'
