I do not pretend to understand the intricacies of e-plain's
implementation of multiple columns, nor of Knuth's \beginsection
macro, but replacing the latter does not help; the problem can be
easily resolved, however, by replacing lines 440--446 of your
original with :<br>

<pre wrap="">I'm experiencing a bad effect when using the eplain command \doublecolumns.
It's visible on p.3 of the dvi output of the following test file to be
processed with simply `tex test': the last line of p.3 falls down beyond the
page limit, below the page number. Please help avoiding it if possibile. The
eplain version is 3.8 dated May 12, 2016. The file includes some latin
characters, but they should not have to do with the problem.
