I looked at grep and gnus group buffers which have been presented
as examples of the problems with the follow-link property.

In both cases, the follow-link property is set to "mouse-face"
meaning that only areas which have the mouse-face property in
those buffers will map mouse-1 to mouse-2.  

In gnus group buffer, the mouse-face is put on the group name only, so
it is easy to set point on a group line without entering that group.

In grep buffers, it seems that (almost) full lines are highlighted
with the mouse-face -- so practically the whole buffer is "mouse-1"
aware.  As I suggested earlier, one simple solution would be to
only put mouse-face on the file:line: part, but this was rejected
by some of you  (who wants to have his cake and eat it too :-)


To me it would be hard to explain to novice users why following a
mouse-face highlighted link in an info or help buffer is "opened" with
a single click, but a similarly highlighted group name in a gnus
buffer need a double click...

If those large areas have mouse-face, it seems appropriate to me.

At least it could be a different mouse-face if they require a double
click.
