Subject: [PATCH] Allow multiple %(expression) instances in
 org-agenda-prefix-format

* lisp/org-agenda.el (org-compile-prefix-format): Use non-greedy match
for %(expression).

Previously, format like "%-12.12s%(expr1) %(expr2)" would not be
parsed correctly because of greedy "(.+)" regexp used to match the
expressions.

Looking at the patch again, I notice that it will break code like
"%((this (has (many parenthesis))))". Though I have no clue how to match
balanced parenthesis using Elisp regexps.

Best,
