This gives us more room to breath with tty names, especially with drivers
that support large numbers of ports.. eg: specialix and digiboard.
This does not actually change the current tty names, it just allows room
for reporting more characters if the drivers use them.
When comparing my recent parser change against the ash in 1.1.5.1, i
found that a couple of other problems in the same area has been fixed
there, but not in 2.2. Semicolons and EOF do also delimit words...
The && and || tokens do also terminate a command, not only the
newline.
While i was at it, disabled trace code by default, it served no good
purpose since it required the use of a debugger anyway to be turned
on. Instead, placed a hint in the Makefile on how to turn it on.
This makes the shell ~ 10 % faster and ~ 4 KB smaller. :)

Turns out, it's pretty important if you use PAX for backup. In the man
page for PAX, there is an error (OK, we could call it a "potentially
catastrophic incompleteness"). It reads:
> The command:
>
> pax -r -v -f filename
>
> gives the verbose table of contents for an archive stored in filename.
Yup, it does do that. With a side effect: it also _replaces_ all the
files that come in from the archive. As is my custom, I did my
backup-validation real soon after the backup was written. Precisely
because I've seen the same sort of thing happen on other systems. So all
that file-restoring didn't do a lot of damage. Probably helped my
fragmentation somewhat (aha, an online defragger?) It did confuse one
hapless user, who lost an email message he _knew_ he hadn't deleted.
Apparently the system restored the file as of just before that critical
message came in.
The correct entry should read:
> The command:
>
> pax -v -f filename
>
> gives the verbose table of contents for an archive stored in filename.

comparisions have been made as string comparisions, even in cases
where both operands clearly qualified as integers.
The fix is to make the parser properly analyzing whether an operand is
a valid integer or not.
stream, such as a rsh or vi pipeline.
The error message is:
stty: TIOCGETD: Operation not supported
It's immediately obvious to the knowledgable hacker type, but not
exactly comforting to the user who's not native to unix. It's
especially confusing if there's a stty command in their .cshrc and
it's showing up on rsh output.

cpio/copyout.c:
Don't output a file if the major, minor or totality of its rdev would be
truncated. Print a message about the skipped files to stderr but don't
report the error in the exit status. cpio's abysmal error handling doesn't
allow continuing after an error, and the rdev checks had to be misplaced
to avoid the problem of returning an error code from routines that return
void.
pax/pax.h:
Use the system macros for major(), minor() and makedev().
pax already checks _all_ output conversions for overflow. This has the
undesirable effect that failure to convert relatively useless fields
such as st_dev for regular files causes files not to be output. pax
doesn't report exactly which fields couldn't be converted.
tar/create.c:
Don't output a file if the major or minor its rdev would be truncated.

(it recovers some disk space) and many bad ones:
- special files are unlinked after certain errors.
- the data may not be recoverable if the source is a special file or fifo.
- unlinking destroys the target attributes as well as the target data.
- unlinking doesn't actually remove the target data if the target is multiply
linked.
There is a bug in sh: the built in command "fc -l" generates
a core dump (*NULL in not_fcnumber).
According to the sh manual page (fc -l [-nr] [first [last]]), fc -l

but fails when first is not given.
