Add a grep mode/compilation log

[anonymous]

Possibly related to #289 (the error log minor mode for Python scripts) I just discovered grep mode in XEmacs. It's basically a mode that shows filenames and line numbers and opens up a new (or existing) buffer and takes you to that line when clicking on it.

For a grep mode, a control minor mode that has the grep controls would be good, because the major mode would be an STC.

Here's what describe-mode has to say about grep mode:

Major mode for compilation log buffers. To visit the source for a line-numbered error, move point to the error message line and type return, or click on the line with button2. There is a menu of commands on M-x compile-popup-menu. To kill the compilation, type C-c C-k.

Probably not for 0.7.1, though.
