I think that the fact that the help window obeys the 'splitbelow'
setting is the desired behaviour, and that the text under ":help :help"
(and maybe at some other places) has not been updated due to an
oversight at the time the 'splitbelow' option was introduced.
I use the following to open the help window at the very bottom when I
use F1, ":h" or ":h {subject}" (typing ":help" in full would revert to
default behaviour); you could use the :abo[veleft] prefix instead of
:bo[tright] to open just above the current window instead. Only if there
is no help window yet, of course: an existing help window in the current
tab page will always be reused, as mentioned in the help text you quoted.
" open help window at bottom unless :help typed in full
if version < 700
cnoreabbrev h bot h
else
cnoreabbrev <expr> h
\ ((getcmdtype() == ':' && getcmdpos() <= 2)? 'bot h' : 'h')
endif
map <F1> :bot help<CR>
Best regards,
Tony.
