  i *know* i've been in this discussion before, but i don't remember
where, i *assume* it was on this list, and i recall someone (again,
don't remember who) who opined that there are two categories of files
that are "known to git":

  1) files known in a *positive* sense, those being explicitly tracked
  files, and

  2) files known in a *negative* sense, as in explicitly ignored files

can anyone refresh my memory if that happened here, and whether that
was the consensus after the discussion was over? if that's the
definition that's being used, then this passage makes sense:

  "Normally, only files unknown to Git are removed, but if the -x
  option is specified, ignored files are also removed."

that pretty clearly implies that ignored files are considered "known"
to git.
