>What worries me is that I never saw any patch #1 ...

Yes, Brandon Allbery (moderator of comp.sources.misc) pointed this out
to me as well. As a result I believe he will be posting both patches #1
& #2 in comp.sources.misc sometime in the future, but here they are in
comp.bugs.misc for all you people out there who can't wait. It looks as
though a malier problem prevented patch #1 from getting out of
Bristol.  Official patch #1 is appended.

If you're confused by all this, you have my humblest apologies.
(Simply, apply the following patch #1 to the original source and then
apply patch #2 to get the latest version.)

-------------------------------------------------------------------

Enclosed is the first official patch to thack, a troff to postscript
filter, recently posted to comp.sources.misc. The patches below fix 2
problems:

1) The length of US paper is different (11") to that of European A4
paper (11.5") - Added an option to the Makefile to use US page
lengths.

2) A variable (fh) was not initialized to 0. This caused problems (core
dumps) on some systems (notably, not ours) and not others. This
variable is now initialized.

Thanks to all of the people who have made favourable comments about
this program.

Apply the following fixes using the program patch or by hand.
