* lisp/org-macs.el (org-matcher-time): Handle hour ("h") time stamp
modifier.
* doc/org-manual.org (The date/time prompt): Document hour modifier.
This adds support for date expressions such as +12h to
org-matcher-time. The regexp this function uses to parse such relative
expressions already includes the "h" character but doesn't actually
handle that case.
AFAICT org-mode commit ec921a2a68 ("Support hourly repeat cookies")
neglected to add support here.
