*double take*

Hmm, I didn't consider the pattern matching aspect when I suggested using
associative arrays.  But since the existing hashtable code provides an
interface for pattern matching lookups, it shouldn't be difficult to
provide a user interface.

What you need there is for the user-defined completion function, after
recognising the "-exec", to recursively invoke the completion mechanism
on the restricted range of words.  As long as completion can be invoked
recursively, there's no need for more specific support for this type
of construct.  (Consider also how to properly handle completion of the
word after "sh -c".)
