979cc2cf2b Don't dereference a NULL pointer in the case of a null pipe.
e.g.:
ls |> foo.out

sh now behaves the same as it does under SunOS 4.x for this case.

4ff02b02ed 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...

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. :)

4f47bf958d sh(1) incorrectly ignored an EOF condition when looking for the
closing backquote in a `foo` substitution.

5eb9106466 Fix /bin/sh's broken handling of the builtin getopts(1). The options
``-ffoo'' and ``-f foo'' have been treated differently.

This has been in violation of Posix.2 (that deprecates -ffoo, but
doesn't disallow it).

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.

5c96f27c9c What I think is a more correct fix for the handling of backslashes
inside backquotes. Reversed my previous fix.

b8ab9277ff Add end of line check so mkinit doesn't produce garbage if you have a
MKINIT line that doesn't have a comment on it (we have at least two).

This mkinit program was written by someone who obviously doesn't believe
in defensive programming. :-(  There's a LOT of work that needs to be done
on this thing. :-( :-( :-(

0ba930fc76 Get this braindead, mongoloid shell look in /stand for pwd if it can't
find it in /bin.  This is something of a kludge, I know, but consider
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
with.

600b25e2d3 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).

4b07d8e782 Add dependencies on libraries to DPADD. Someday this should be done
automagically.  -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.
