I'd like to embed several \if\else\fi groups, but it doesn't seem to
work.  For example

\iftesta ...
	\else ...
	\iftestb
		\iftestc ...
		\fi
	\else ...
\fi

I keep getting error messages about extra \else's.  I'm sure the
\if's, \else's and \fi's are matches.

I think what's might be happening is that TeX is ignoring the embedded
\if's if the first test fails, and then seeing the embedding \fi, and
thinking it matches the matrix \fi.  Is this so?  Is there a
workaround?
