   I just tested removing the default-directory line and
   locate.el seems to work fine. I believe that it uses
   dired-move-to-filename-regexp to determine the file
   name, so default-directory would be ignored in any
   case, and as best I can recall, it was only set to get
   dired-mode to work properly.

   The value of default-directory is now "~/".

If you remove the line, the value of default-directory is going to be
whatever the value was in the buffer from which `locate' was invoked.
(Which may not be that bad if nothing better is available on MS Windows.)

I do not see however why one should fail to make dired mode work as
best as it can on those operating systems that support it, such as
GNU/Linux and Unix.  So one could do something like the patch below.
Maybe some other operating systems might have to be added to the
'(ms-dos windows-nt cygwin).
