lynx-dev [PATCH 2.8.5-dev15] table cleanup

[Ilya Zakharevich]

This fixes (a rare) segfault.  The actual reason for this segfault is
that lynx ignores non-breakable space in most situations; the table
logic was not expecting this, thus a branch was entered which should
not have been entered at all.

Until the question with non-breakable spaces is resolved, this fix
hardens the branch in question so that it does not break even if
entered this way.  ;-)

Enjoy,
Ilya
