Testing if the DISPLAY variable is set (or rather, that it's length is
non-zero). Testing the DISPLAY variable is a nice sneaky way of testing
"am I in an X session?"

If the test fails by the way, the mailcap will proceed to the next one,
so I have

text/html; /usr/bin/galeon '%s'; description=HTML Text; nametemplate=%s.html;test=test -n "$DISPLAY"
text/html; /usr/bin/links '%s'; needsterminal; description=HTML Text; nametemplate=%s.html
text/html; /usr/bin/links -dump '%s'; copiousoutput; description=HTML Text; nametemplate=%s.html

so it will only use Galeon when in X and links otherwise (this also has
the nice effect that when combined with 'auto_view text/html' in my
.muttrc, it will use links to dump the HTML to text, lynx can do the
same thing).

I HEART mailcap.
