5557a02a60 Be more consistent with handling of quote mark control character.
Don't output double-quotes inside variable expansion/arithmetic
expansion region in here-documents.  When leaving the arithmetic
expansion syntax mode, adjust the dblquote flag according to
previous syntax, in order to avoid splitting of quoted variables.

6f47734fd7 Better handling of word splitting. Don't record the same region
multiple times when performing nested variable expansion, and
preserve some quoting information in order to avoid removing
apparently empty expansion result.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

1018bd8d3c ack! back these out so I can see what I did wrong. It looks like a
patch-by-hand botch, but it sig-11's during make world.

4417f6297d Fix for PR#1287. This makes sh behave sensibly in case statements in the
face of aliases.  Note, bash doesn't do aliases while running scripts, but
"real" ksh does..

Also:
  Reduce redundant .Nm macros in (unused) bltin/echo.1
  nuke error2, it's hardly used.
  More -Wall cleanups
  dont do certain history operations if NO_HISTORY defined
  handle quad_t's from resource limits

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..

0f9a535124 Fix the borokeness that crept in with rev 1.10 of parser.c, the sh
didn't correctly start background jobs anymore.  Strange that nobody
was complaining...

Add a dummy target for `builtins' in the Makefile, to prevent it
from attempting to build this file by compiling builtins.c. :-/

454bd7b924 The shell incorrectly gave & precedence over ;. This breaks the
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.)

248ffae537 Sigh. This will become a never ending story. :-(
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...

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. :)

650488feaa With '!' being made into a keyword (yech!), case cases didn't work properly.
This should fix it (passed my test cases).  Originally discovered with
perl's Configure (well, in FreeBSD, I don't know how the NetBSD folks
discovered it).
