Definitely.

It would also be nice if just `C-u' as a prefix argument for previous-error
had a special meaning, like it does for next-error.  I'd like it to reparse
the error messages and move to the last error, but that is a bigger change
and harder to implement.  The difficulty is that compilation-next-error-locus's
MOVE and REPARSE arguments are not orthogonal:

  (compile-reinitialize-errors reparse nil (and (not reparse) (max 0 move)))
