I like it precisely because I can write any command I want ;-)
For example, I can use grep, egrep, fgrep, with/without case
sensitivity, with/without context lines, ...

Hopefully we can merge some of that functionality into eshell's
command completion and use eshell's completion for M-x grep (and
M-! and M-| and M-x compile and ...).

It hasn't been rewritten at all.  I've just slightly improved the default
command offered when you hit C-u M-x grep.  A couple one-liners at most.

It would be great to use jit-lock for *compilation* buffers as well,
but a lot more work than for the specific case you're dealing with :-(

That might be a good feature as well.  I have a similar feature for
sml-mode where the compiler's output includes a start and end point
for errors (the type-inference algorithm used by the language means
that some type errors are difficult for the compiler to locate).
But it's an ugly hack.  We should make such support more widespread
for all compilation buffers.

I tend to agre.  Maybe we should just change it.  Or move the M-g prefix
to the beginning of the line (so it appears only once).
