bug#7726: reveal-mode bypassed by compile-goto-error

I think the problem is that reveal-mode runs from post-command-hook and
reveals what's in the buffer that's current when post-command-hook is
run, whereas in the above cases, the buffer that needs revealing is not
current at that point.
That's one of the cases where we could use something like
a "pre-redisplay-hook".
