New slant on the "Second tuesday of the month" problem

["Daniel J. Sinder" <djsinder@gmail.com>]

The question of timestamps for events that occur based on the ordinal 
count of weeks in the month (e.g., "every second Tuesday of the month") 
has come up several times before.  The bottom line is that a diary sexp 
has to be used, and I understand that.

This is fine for, say, U.S. election days ("Tuesday after the first 
Monday of November") because they are never postponed.  However, some 
repeating events like this (like work meetings) occasionally get 
postponed a day or two.  Normally, I use multiple headings for repeating 
events that have this problem, which is easy thanks to 
org-clone-subtree-with-time-shift.  With this, I can shift any given 
occurrence right from the agenda, and even add meeting notes to the 
headlines for specific meeting occurrences.

How can I achieve this with an event that *requires* a diary sexp?  In 
essence I would like a function 
org-create-subtree-clones-from-diary-sexp that would generate N 
headlines for the next N occurrences of the event in an sexp.  Or, is 
there another way to achieve this?

Thanks,
Dan
