Suggested default change for browse-url-browser-function

[Lars Magne Ingebrigtsen <larsi@gnus.org>]

I was wondering where to plug in the correct mailto: behaviour in
shr.el, and it strikes me that perhaps this should be left to
browse-url, since that's controlling all the other url-browsing
behaviour.

So with that in mind, I propose the following change.  It means that
anybody who uses browse-url on a mailto: link in Emacs will end up in
Message mode by default instead of popping up a browser.

The downside to doing it this way is that (I think) many people have
already set `browse-url-browser-function' to something else, so changing
the default won't actually have any significant effect, and mailto:
links still won't work for many people.
