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

christos 3d5f212ba8 enable parsing of multi-digit positional arguments i.e. ${10} works and it 
is not a bad substitution.
