Or, rather more helpfully : \exhyphenpenalty is the
penalty that is applied if a line is broken at an
explicit (whence the leading "ex") hyphen. What
The TeXbook actually says (p.~96) is "Each potential
breakpoint has an associated 'penalty' which represents
the 'aesthetic cost' of breaking at that place. [If a
line break occurs at a discretionary break], the penalty
is the current value of \hyphenpenalty if the pre-break
text is non-empty, or the current value of \exhyphenpenalty
if the pre-break text is empty."
