Certainly not intentional. I forgot to make sure that `compadd' knows
that the strings contain parts separated by slashes.

Ick. I can't reproduce this, but...

Are you sure it hangs? Or is it just incredibly slow? For me, the lack
of speed comes from the size of the directories `/usr/s*'. Also, there 
was a problem with building a pattern that is used to remove unmatched 
strings over which I stumbled when trying the same (`/u/s/<TAB>'). The 
problem was that I used `${(@M)tmp1:#(${(j:|:)~tmp2})}' where I should
have used `${(@M)tmp1:#(${(j:|:)~${(@)tmp2:q}})}' to make sure special
characters in the filenames are not taken as pattern characters.

Still, I would like to know where it got stuck.
