>Description:

As seen in PR 51696, vertical bar characters in COMMENT cause
problems; it would be nice if pkglint could warn about this.

(also, as also seen in PR 51696, the presence of a # on that line is
probably an error rather than a comment and it might be worth trying
to diagnose that too; but that could be problematic)
