1. TAB calls completion-at-point 2. completion-at-point calls pcomplete-completions-at-point, which calls pcomplete/cd; this completes the directory nameSounds like a bug: the `completion-at-point-functions` should not perform the completion but should only return a description of the part of the text that is the subject of completion, along with a description (generally in the form of a function) of the set of elements from which the possible completions can be taken.
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).
