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

[Luc Teirlinck]

>From my previous message:

   In as far as `locate-in-alternate-database' is concerned, I can not
   test this function since it only works for GNU locate and I have
   slocate installed.  Since the docstring does not mention a prefix arg,
   I am not even sure that this function can handle one at all.

   So the currently committed patch does not pass the arg along.

   IF somebody would be able to check that the following patch works OK
   in the four combinatorial cases (prefix arg vs no prefix arg,
   `locate-prompt-for-command' nil vs t), one could commit the patch
   below

Thinking more about this, I now believe that a numeric arg to this
function makes little sense, even assuming that it _would_ work OK,
nor does using this function at all with `locate-prompt-for-command'
set to t make much sense.  This function is nothing more than an
interface for specifying the `d' option.  If you want to specify the
exact command line given to locate, then you can quite as well specify
the `-d' option right then.  This is actually more convenient than
specifying the database at a separate prompt.  Moreover, if you
specify the `-d' option explicitly, `g' will work correctly, whereas
if you use `locate-in-alternate-database', it probably will not.

So I do not believe that there is any need to test the patch for
`locate-in-alternate-database' which I proposed.  I believe that it is
better to just forget about that patch.

Sincerely,

Luc Teirlinck.
