f831af1d64 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.

5ec5b27841 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

5195be912e 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..

82eac92f0e 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.

944d729639 Implement the "ulimit" builtin. This is the analogon to csh's "limit"

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.

3de11c3b09 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. :)

0011fb1aae From "Philippe Charnier" <charnier@lirmm.fr>:
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
is a correct sequence (in that case, values are defaulted to -16 and -1)
but fails when first is not given.

0ba930fc76 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
