958ba632fa Make sh(1) a little braver in the face of adversity. sh(1)
now handles the getpwd() init problem the same way as bash
and ksh do.  Also while I was in here, I cleaned up the format
a little, removed some unnnecessary #if SYMLINKS cruft, and
changed the pwd builtin to use getcwd(3) as Joerg suggested.

93d0e5ef14 Fix a problem caused by finger failure on my part. The builtin
getopts should now work as expected.  This fix was in the NetBSD
code that I was merging from but missed getting into FreeBSD's
version because of 'drain bamage' on my part.

7a2ce49ee0 Back out rev 1.7 which was to fix PR#1206 (to be reopened).
This patch causes too many side effects, one of which bites hard is
when interrupting a 'make fetch' in the ports tree (PR#1990).
This whole area is a real can of worms....

This most definately should go into 2.2

aa9caaf657 Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning. This is a
merge of parallel duplicate work by Steve Price and myself. :-]

There are some changes to the build that are my fault...  mkinit.c was
trying (poorly) to duplicate some of the work that make(1) is designed to
do.  The Makefile hackery is my fault too, the depend list was incomplete
because of some explicit OBJS+= entries, so mkdep wasn't picking up their
source file #includes.

This closes a pile of /bin/sh PR's, but not all of them..

8f08f33ed9 Implement allowing 'set -v' in the middle of a script to work.
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.

7a2afe644c Implement the "ulimit" builtin. This is the analogon to csh's "limit"
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.

47a052e00f Make the shell handle a null command in a &&/|| sequence correctly.
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. :)

beeac5cded Get this braindead, mongoloid shell look in /stand for pwd if it can't

my limited alternatives:  I can't make this an execvp() without making
people scream that I introduced a failure point or slowed down pwd,
and I can't make it an optional macro since crunch doesn't let you pass
arbitrary command-line args to the build of one of its crunch-ees.
This is the simplest, if not the nicest looking, solution I could come up
