This patch proposes the addition of a new Eldoc function
`help-at-pt-eldoc-function'.

Show help-at-pt string via Eldoc as an alternative to the
`help-at-pt-display-when-idle' timer.  The help-at-pt timer competes
with Eldoc for the echo area, such that using both does not work well.
The new `help-at-pt-eldoc-function' is meant to be added to
`eldoc-documentation-functions'.
