- Nope, it's not TexEdit that is doing it, but a bug in Executor 1.99q.
- This bug has been fixed internally (and in Executor/NEXTSTEP 1.99q2)
- but I didn't realize it was causing problems, so I haven't yet made a
- 1.99q3 for Linux, but I can probably do so in the next 24 hours.

- Revert to 1.99p9, wait for 1.99q3 or write a shell script that filters
- out our botch.
-
- Programming commentary follows -- feel free to skip this:
-
- Although many of our bugs are incredibly esoteric and not worth
- explaining to the programmers out there, what happened is that when we
- adjusted our PostScript printing code to work again under NEXTSTEP we
- changed a line that used to say (approximately):
-
- fprintf (printer, PROLOG_STRING);
-
- to
-
- fprintf (printer, "%s%s%s", PROLOG_STRING_1, PROLOG_STRING_2, PROLOG_STRING_3);
-
- since we had to break the prolog into different parts (under NEXTSTEP
- we only need part 2, I think). However if you do such a thing,
- breaking the initial string into three pieces isn't sufficient, since
- the original string had to have %% for each % since it was the format
- argument to printf, rather than a literal argument to be printed by
- %s.
-
- Pretty embarrassing. It slipped by our testing because our printer
- doesn't auto-detect PostScript, we just use a variant that always
- expects PostScript.
