A function I've written (called #’man-spot) allows me to make notes in
commentary which look like this:

;;; (man-spot "openssl" "^ +s_client")

for example.

By evaluating this form, I'm able to jump to the specific point in the
openssl manpage which describes the s_client command.

The second argument to #'man-spot is a regular expression which is
passed to #'re-search-backward.  This only works if #'manual-entry has
finished putting the manpage into a buffer.  Hence the preference for
a synchronous call to #'Man-getpage-in-background.
