Is that not so? Yes, the problem is the same for the deprecated envvar GREP_COLOR and a newer envvar GREP_COLORS. I understood that part of the complaint was using the deprecated envvar GREP_COLOR instead of newer GREP_COLORS. Since Emacs sets both there is no problem for supporting old and new versions of GNU grep. As for the main problem, Stefan suggested a workable solution. -- Juri Linkov http://www.jurta.org/emacs/
