[ splorf... ]  But really, \fi is something that could only be loved
by a certain academic breed of hackers.  I'd go for \endif, probably.
That still doesn't relate well with \unless, so +1 for \if, \ifnot,
\else, and \endif.

I'm not really convinced that we need an \elseif at this point.
It could be added later if people find it compelling, but I'm
having a hard time believing that it's essential.
