Re: patch for locate.el when called with prefix arg

[Luc Teirlinck]

>From my previous message:

   I believe that _instead_ of applying your patch, the apparently
   misguided 2006-09-09 changes should be completely reverted (before
   releasing Emacs 22), getting rid of all three _regressive_ bugs we
   know about, as well as of those we do not know about yet that were
   introduced by that change.

I know see that these changes were made to address the following problems:

    Reverting Locate mode buffers (via locate-update) currently ignores
    filters from locate-with-filter.  It also doesn't work with uniquely
    renamed buffers, or when locate has been called non-interactively
    (e.g., from eshell/locate) and locate-history-list and
    locate-grep-history-list aren't modified.

These problems can, and should, obviously be addressed in locate-update,
without affecting other stuff.

Anyway, the problems described above are not regressions and could be
fixed properly after the release (or before, but that would imply a
delay), whereas the problems introduced by their "fix" are
regressions, at least two of which are currently not fixed.  (And
looking at the code, I strongly suspect that these two bugs are not
the only ones.)

Sincerely,

Luc Teirlinck.
