csh bug fix
A heinous bug has been found in the csh. The routine syntax() expects
3 parameters and is only called with 2, when called non-recursively,
eg in sh.c. The third parameter is a word of flags. The fix is to
replace calls of syntax(p1, p2) with syntax(p1, p2, 0). The bug was
found when I was trying to follow the directions in the distribution
about making a non-i/d csh (loaded -n). Works fine, now.
Other hints for non-i/d csh:
1. To reduce size, reduce size of most of the error messages, eg, replace
"Ambiguous" with "Ambig."; also there are several obscure things which
can be commented out such as execl's of several versions of newgrp in
sh.misc.c and the -q option in sh.c.
2. DONT define BBGETPW in getpwent.c (if you want "~" to work), but DO use the
provided get*.c.
3. Default internal buffer size should be 512, not 1024, as the distributed
makefile makes it. A larger buffer size causes complicated parsings
(source x; x has set y=~foo...) to run out of memory. On the other
hand the distributed termcap entry for televidios has a termcap >
512 bytes (the buffer size is the size of a csh "word") which causes
the shell to say "word too long" when doing a source of a tset v5 -s.
But, its easy to write a termcap for televidios which is alot shorter,
or you can trick csh in other ways. We have hp's, falco's, and concepts,
for intelligent terms, and those termcaps work fine.
