Hi,
yes, that's right, I want the information in the header line only.

That's right, but I'm using ElDoc not for Emacs Lisp, but with
c-eldoc[1] to display C function signatures, or anything C-related
that's at point.
I don't like it if ElDoc is overwriting all the time the messages in
the echo area, the header line is a better place for that (I think),
but only since it's rarely used (and thus it's never overwriting
anything).

I can try, but my Emacs Lisp knowledge is quite limited, I'll try to
come up with something customizable and I'll post it here for review
:)
Geralt.
P.S. It's Geralt with a t at the end (and don't worry, no offensive taken!).
