5accccd051 Fix problem introduced in yesterday's commit that broke both signed and 
unsigned character machines. So that people don't have to reverse engineer
this again:
	mksyntax detects if characters are signed or not and builts a syntax
	table that has a base of 129 for signed characters or 1 for unsigned
	characters. This is so the largest negative signed char [-128] + the
	base == 1. 0 is special and means end of file in both cases. PEOF
	is -1 for the unsigned character case and -129 for the signed
	character case, so that syntax[PEOF + base] == syntax[0] == CEOF
	So PEOF has to be -1, but it is explicitly compared with
	unsigned characters on machines where characters are unsigned.
	The quick fix is to define UPEOF the (unsigned char) version of PEOF
	and use that. A better fix is to always use unsigned characters
	when referencing symbol table entries, but that would require
	extensive changes to the shell. So to summarize

	syntax[0] == CEOF, base + PEOF == 0

		unsigned	signed
	base	1		129
	PEOF	-1		-129

5678a13f1b Re-introduce some code from 1.14 (with modifications) to make the 
shell's idea of the current working directory match reality when
symlinks (or anything else we can't stat) are traversed with the
cd command. However, this does not print out the cwd after cd
traverses symlinks, as it used to, though the capability is still
there should one want to use it.

0bc88b2434 getopts fixes: 
1. OPTIND value was not computed correctly when the argument was part of the
   option string (i.e. for "l:" "-l 1" was working "-l1" was not). (PR/2505).
2. OPTARG was not being unset in case of errors [in the non POSIX error case].
3. optvar could be set to random values.
4. Option string starting with a : was not treated specially as POSIX
   specifies (if the option string starts with a :, then there is no
   error printed when there are missing option arguments or illegal options,
   and OPTARG and optvar are being set specially).
5. Implemented getopts "opts" optvar [arg]. The optional argument case
   was not implemented.

To do:
- what does Posix say about resetting the getopts state? Bash does it
  by setting OPTIND=0; is that correct? Should we be doing the same thing?
- should we be using getopt(3) for everything internal to the shell? Is that
  feasible because we might need to handle multiple invocations at once.

893ade3fac - fix PR1620, -DNO_HISTORY did not work. 
- restore parsing state after parsing old style command substitution.
  The ';' in '`echo z;`' broke the following:
	for i in 1; do
		cat > /dev/tty << __EOF__
		`echo z;`
		__EOF__
	done

cVS: Enter Log.  Lines beginning with `CVS: ' are removed automatically

81a152541e Kenneth Stailey pointed out that his previous fix was incorrect. RE and SL

731f8de0fa as suggested in PR 1347, by Kenneth Stailey, make "RE" and "SL" fields 
show up as two digits, max, displaying "99" if > 99.  allow any field with
an unsigned value to be specified as printing that way (though right now
it's only used for RE and SL, which are both unsigned longs).  This fix
is substantially different than that suggested in the PR.

bdf0a24b3d Don't remove the destination file if there is a write error. This is 
very bad if it is actually a device or fifo.  POSIX.2 requires that a
diagnostic message be written, the file descriptor be closed, and for
cp to continue on with the rest of the files.

23e6aab105 Use "utility" instead of "command". Modern definitions of these terms 
are distinct (See POSIX.2 glossary).

A utility is a executable, script or shell builtin; while a command
can be any of those things plus lists, pipelines, compound commands
(if, for, while) and shell function definitions.
