[pdftex] Strangeness with protcode

[David Wooten]

Greetings,
I'm hoping there is something obvious that I am missing... The output 
from the following sample has lines which protrude too 
far---significantly. This has not happened with any other files, and I 
cannot seem to figure out where the difference is.  Thanks for any 
advice you can give me!


\documentclass[twocolumn]{book}
\input protcode.tex
\pdfprotrudechars=2
\renewcommand\familydefault{ptm}
\def\setupfont{
         \setprotcode\font
}
\def\setupfam{
         {\setupfont}
         {\itshape\setupfont}
         {\bfseries\setupfont}
         {\itshape\bfseries\setupfont}
}
\AtBeginDocument{
         \setupfam
         \large\setupfam
         \small\setupfam
}
\setlength{\columnsep}{0.4in}
\setlength{\parindent}{-0.1in}
\def\b#1{{\bfseries#1}~}
\def\ib#1{{\itshape#1}}
\small
\begin{document}

               skill or know-how or authority to do something; ``able

        \ib{3:} having inherent physical or mental ability or capacity;
           ``able to learn'' ``human beings are able to walk on two
