Please don't take my words too literally.  "This completes the directory 
name" does not mean that `pcomplete/cd' performs the completion itself. 
Indeed it returns something with which the completion is performed.

The bug is clearly not there (at step 2), but later (in the fact that 
`completion-at-point' calls `pcomplete-completions-at-point' three times).
