I see.  I don't know whether that happened.  But could well have, within the
internal file-name completion code.  I was testing with input "~" (i.e. not a
file name in the default directory), so it might well have gotten to a point
where it checked the files in my home dir, though the completion was initiated
in a subdir.

That btw is not a rare occurrence at all.  Dunno whether it corresponds to what
you are describing, but it is not rare for a user to change the minibuffer input
to an absolute file name in some directory other than the one where the command
was invoked.

HTH, but I doubt it. ;-)
