Hi Eric,

thanks for the suggestion.  I had considered the idea for a second, but
failed to see the nontrivial half.

If the parameter may be expected to be very long (which I don't think it
will be) then
  func_append patt '?'

would be useful here, and even if not, appending rather than prepending
here helps with current bash.
