Subject: grep column counting is broken in Emacs 24

From: Le Wang <[email-masked]>

Reproducible in very recent build as of this message.

The effect of this bug is when I click on a grep target the point moves to
one in front of the match.  (assuming compilation-first-column==1, which is
the default)

Details:

`compilation-move-to-column' always references `compilation-first-column'
when calculating columns.  It should not for "grep" output, because the
column # is calculated by `grep-regexp-alist'.
