`turn-on-eldoc-mode' obsolete?

[Rüdiger Sonderfeld]

Hello,

in r116095 the function `turn-on-eldoc-mode' was replaced by an alias for 
`eldoc-mode' and marked obsolete.  There was no entry in the ChangeLog for 
this and I don't understand the reason.  It seems several minor modes provide 
a `turn-on' function to avoid the toggling behaviour of the minor mode command 
(e.g., turn-on-auto-fill, turn-on-flyspell, etc.).  Which is quite useful for 
mode hooks.

I think `turn-on-eldoc-mode' should be restored or there should be a common 
decision on `turn-on-*' functions for minor modes.

Regards,
Rüdiger
