I applied the patch. Page 1 of the printout has 54 lines, Print Preview has 56.
The vertical line on Print Preview looks fine, on the hard copy it appears on top of the least significant digit of the line number. For example, on line 1, the vertical line is superimposed on the vertical line that comprises most of the 1's glyph.
The vertical line extends down "a ways" past the last line number. On Print Preview, it extends what seems to be one line height, or so. On hardcopy, it extends what might be three lines, its difficult to measure. Perhaps it is drawn to the top of the page number row, but the last printed line is one line less?
Anyway, the good news is that my test doc, page one anyway, does not wrap.
