I thought this would be a nice extension to an existing customization
option for org-agenda. Commit message has an example and rationale.
Comments and amendments welcome, of course. I signed FSF copyright
assignment previously. Thanks, Chris

* org-agenda.el (org-agenda--insert-overriding-header): Allow
`org-agenda-overriding-header' to be a function in addition to a
string or nil. When the custom agenda is created or updated, call that
function and insert the string it returns as the agenda header.
This allows custom commands to produce dynamic headers that include
up-to-date information. For example, this produces a header with a
current timestamp:
(push '("DHD" "Dynamic header demo"
((alltodo
""
((org-agenda-overriding-header
(lambda ()
(propertize
(format-time-string "-- Get crackin’, it’s %H:%M:%S!!\n")
'face 'org-agenda-structure)))))))
org-agenda-custom-commands)
User is free to add any face properties, use Org links, and include a
blank line or not. I am using this to count how many items are in
various inboxes and display them in an agenda.
