bug#52: FW: [mouse-1 in Customize should respect mouse-1-click-follows-link]

Yes, Custom has always used mouse-1 clicks for that purpose, AFAIK.

This is supposed to let mouse-1 clicks follow links otherwise only
accessible via mouse-2 clicks (i.e. when there's no binding for mouse-1
on this button/link).

It relies on the `follow-link' text-property and/or key binding to
specifies when this fallback is applicable.

That was introduced in reaction to people complaining about the
non-standard Emacs convention of using mouse-2 to follow links.
But actually some part of Emacs already used mouse-1 to follow links,
such as Customize, so these aren't affected by
mouse-1-click-follows-link.

I think in this present case, Custom should better follow Emacs
conventions and hence only bind mouse-2 and then rely on the follow-link
feature to make mouse-1 also work for those users who like it.
