Description: Fixes segmentation fault caused by large EPS
Running html2ps on files with largish EPS images (using the --original
option) can cause the program to segfault. After some examination with
perl -d and gdb, it turned out that perl's regexp matching engine blows
the stack with thousands of frames. The following trivial patch seems
to fix the problem, and it also makes EPS handling noticeably faster
diff --git a/html2ps b/html2ps
