`-u' and grepping for the username. Basically you can now get a short
`ps -x' like list (with more space for the command) for other users.
traditional behaviour, and it violates Posix.2.
Fixes PR # bin/880: /bin/sh incorrectly parse...
Fixes also an earlier problem report about the shell not evaluating
loops correctly. (Not files via GNATS.)

This means that a script containing:
echo 1
set -v
echo 2
will now produce output, like it does on SYSV machines and other 'proper'
/bin/sh implementations..
This is done by a slight restructure of the input processor allowing it to
read chunks from the file at a time, but process the data by line from the
chunk.

o fix brokeness for 1>&5 redirection, where `5' was an invalid file
descriptor, but no error message has been generated
o fix brokeness for redirect to/from myself case
command and badly needed in sh(1) for everybody who wants to modify
the system-wide limits from inside /etc/rc.
The options are similar to other system's implemantations of this
command, with the FreeBSD additions for -m (memoryuse) and -p (max
processes) that are not available on other systems.
`mv foo/ ../..' to `mv foo/ ../../foo/', not to `mv foo/ ../../'. The
latter caused a panic. Before the trailing slash changes in the kernel,
the trailing slashes caused the rename() for this mv to fail earlier, so
there was no panic in 2.0.
Fixes part of PR 760.

David Greenman pointed out that when a process that had been revoked from

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.
