[tbl]: Add test case.
* src/preproc/tbl/tests/do-not-overdraw-page-top-in-nroff-mode.sh: Add
an eleventh test case, prompted by ascii(7) from Linux man-pages,
where a table with a vertical rule got coincidentally rendered at the
very top of a page (which can only happen in continuous rendering
mode, where the page boundaries are invisible) while no-space mode was
on (due to the table immediately following a paragraphing macro).
Test fails at this commit.
