This appears to fix the problem it sets out to fix, but it looks
to me like there are adjacent problems of the same ilk; do you
feel like looking at those?

Specifically, I wondered whether we had the same bug with table
headers or cells that contain newlines. It looks like
print_aligned_text() is okay, because it counts up those newlines
and includes them in the extra_output_lines value that it passes
to IsPagerNeeded(). But print_aligned_vertical() and printTable()
have no such logic. Am I missing something about why those cases
need not consider this issue? If not, can we fix that by moving
all the "extra_lines" logic into IsPagerNeeded(), and if not
what shall we do about it?
