I don't know anything about js -- is the syntax for a mouseover pretty
much just something in the <IMG> tag somewhere?  If it's something
like that, can try to find the 'mouseover=' text and splice out what's
in quotes after it (dealing with backslashed quotes, etc).

As an easier (and less demanding on screen realestate, and in keeping
with how annoying mouseover truly IS (heh)), how about if a mouseover
just did a temporary message over the existing status line, using the
facilities we currently have?  Could do something like have it write
with the same precedence as informational messages (JSSECS=0 ? Ouch.)
or something. 

Didn't someone recently add a history mechanism for statusline
messages?  If the fake-js is displayed on screen for a configurable
amount of time, and recallable, I think that'd be a nice way to do it
without eating up another line of screen.

I know it annoys me whenever I'm unlucky enough to use one of those
Other Browsers.
