I was afraid of this.  I think the safest way of not screwing up the
parsing and error handling would be to implement it as a patch to
org-activate-*-links in org.el.

I guess I should give some background info.  Lately (>1yr), I have been
using Emacs exclusively from the terminal.  In a gui, hovering the mouse
over a link shows you the target as a tooltip.  If you turn tooltip mode
off, it is shown in the echo area; but this is only in a gui frame.

I think it is very important to show where a link goes in a document.  I
consider it good a safety practise (e.g. web browsers).  Hence my
attempt to implement this feature.  :)

Cheers,
