christos 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

christos 633ceb6db5 - varisset(): In positional arguments, take into account VSNUL so that:
set -- ""; echo ${1:-wwww} works.
- when expanding arithmetic, discard previous ifs recorded regions, since we
  are doing our own scanning. x=ab; echo $((${#x}+1)) now works.
- in ${var#word} fix two bugs:
   * if there was an exact match, there was an off-by-one bug in the
     comparison of the words. x=abcd; echo ${x#abcd}
   * if there was no match, the stack region was not adjusted and the rest
     of the word was getting written in the wrong place. x=123; echo ${x#abc}X

cjs 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.
