+% Allow a ragged right output to aid breaking long URL's.  There can
+% be a break at the \allowbreak with no extra glue (if the existing stretch in
+% the line is sufficent), a break at the \penalty100 with extra glue added
+% at the end of the line, or no break at all here.
+%   Changing the value of the penalty and/or the amount of stretch affects how
+% preferrable one choice is over the other.
