With this modest change, rpm is now able to trigger on 1-of-N  
directories
explicitly mentioned.

E.g.

     %triggerpostun b -- /tmp/test-triggers-+(a|b)/
       echo "--- triggerpostun(b/a) arg $1 $2 ..."

triggers on either of
     /tmp/test-triggers-a
     /tmp/test-triggers-b

Essentially the equivalent of the pattern
     /tmp/test-triggers-[ab]
(which also works) without the messiness of character classes.

Note the trailing /, which implies RPMTAG_DIRNAMES is used.
There's still a bit of work to apply fnmatch to full file paths  
symmetrically.

And the rpmbuild parser (and other locations) likely need to be  
tricked up to recognize
globs like
     +(/bing|/bang|/boom)/foo
as file path expressions.
