varisset fixes:
...
- treat $0 specially since it is not in shellparams
- check the number of parameters instead of walking
the parameters array to avoid checking against the
null terminated element.

- 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

Fixed new bug the previous fix introduced:

false
foo=bar
echo $?
would print 1
Also fixed the long standing bug:
false
echo `echo $?`
would print 0
The exitstatus needs rethinking and rewriting. The trial and error method
is not very efficient
