[tex-eplain] Overflow on \readindex command.

[John Culleton]

I have this sequence of code:

 \vfil\eject
\chapter{Index}

\readindexfile{i}

 \bye

I get this error message:
----------------------------------------------
(./book.ind

                                                  \advance \vsize by -\ht

The file is in \singlecolumn mode at this point. \Chapter is defined as:
