"
    Because grep relies on compilation-mode, which uses font-lock to do
    its work, so it forcefully enables font-lock.

It seems like a bug for it to work this way.

What it ought to do is enable Font Lock in an internal way, so it will
put on font-lock-face properties.  These properties should be created
regardless of whether Font Lock mode is enabled, but they should
only affect display when Font Lock mode is enabled.

I've just pushed a change which makes M-x compile and M-x grep work
without forcing font-lock to be enabled.  They also make the
error-parsing lazier, so it may be faster in some cases (tho probably
slower in others as well: speed was not the main focus of my coding).
