Use the source!

Same as your previous function.  Do you think we remember all these
answers?  It's always the same thing. You want something about
next-error, ok, C-h f next-error RET C-x o TAB RET and read the
source!

Idem here, C-h f describe-function RET C-x o TAB RET and read the doc
and the source!

In my emacs instance, the doc of describe-function  note that it is
adviced.  Perhaps you could do the same, and add an advice to add the
descriptions you want?  (See defadvise).
