It affects M-x shell for me too. Maybe I'm just doing something wrong 
though. I tried this:

   emacs -Q -f shell
   ls -<TAB>

 From that, I get completions like "--block-size=", which doesn't show 
the annotation. With the annotation, it should be "--block-size=SIZE".

Currently, Pcomplete passes the annotation around by propertizing the 
first character of the candidate string. That ends up not working, since 
the completion code uses the characters in the buffer and concats the 
suffix from Pcomplete. So then the pcomplete-annotation almost always 
gets thrown out.

I think a safe (but incomplete) fix would be to put the annotation on 
the *last* character of the candidate string. Then it usually wouldn't 
get thrown out. It won't work in *every* case, but it would only fail in 
rare edge cases.
