--- Comment #3 from wajasu <matted-34813 at mypacks.net> ---
I did write a sub-routine in C4/Labels/Labels.pm that used StrWidth for each
individual character of the specified font/fontsize, such that if it was going
to get truncated, it would scan back to the prior space and wrap to the next
line.  Typically, the title being the culprit.  I did get a word or two extra
in the first line.

I did not add behavior to throw way the second line, if there are more lines to
be written.  I suppose this would also need to content with varying line height
based on the fontsize, because folks might be dropping to a smaller fontsize
(10 is about 4 lines, 6 might get you more).

But my labels are usually:
itemcallnumber, author, title (possible2 lines) in a BIBBAR printstyle.
font Times Roman, fontsize 10.

A title like:
Salty librarians, and savvy cataloguers,
dusty books :

became:
Salty librarians, and savvy cataloguers,dusty
books :

with my proportional wrap.

Let me know and I'll work on sending a patch.
