Ah!  Now that's a nice trick - I hadn't realised you could override
variables like that.  And given that option values are lisp
expressions, one could easily define a group of agenda files via
(defvar my-org-personal-agenda-files) and then use that variable in
one or more custom agenda commands.  Wouldn't that be good enough
for most people who want a file-grouping mechanism?

(I should make it clear that I still believe it's worth making the
tweak we agreed on to support CATEGORY="..." searches which catch
#+CATEGORY values.)
