grep-mode provides a menu item `Repeat grep' which is bound to
`recompile'. But using `recompile' on grep buffers has two problems:
1. grep command repeated with `recompile' uses compilation exit messages
instead of grep exit messages (`matches found/no matches found') which
leads to incorrect fontification.
2. new variable `compilation-disable-input' is nil in grep buffers
when grep is started by `recompile'. This is a minor problem but
it would be good to fix both problems with the following patch
which makes the variables `compilation-process-setup-function'
and `compilation-disable-input' buffer-local in grep buffers:
