Because the parser does not recursively parse parameter expansion
with respect to quotes, we can't accurately determine quote status at
parse time. This patch works around this by moving the quote detection
to run-time where we do interpret it recursively.
Test case:
foo=\\ echo "<${foo#[\\]}>"
Old result:
<\>
New result:
<>
Do not quote back slashes in parameter expansions outside quotes.
Test case:
a=/b/c/*
b=\\
echo ${a%$b*}
Old result:
/b/c/*
New result:
/b/c/

Collapsing arithmetic expansion is incorrect when the inner arithmetic
expansion is a part of a parameter expansion.

unset a
echo $((3 + ${a:=$((4 + 5))}))
echo $a

fixes segfault introduced in 0a0acb55db8d7c4dec445573f1b0528d126b9e1f with functions using "local -".
test-case: f() { local -; local x; }; f
note: with this change applied multiple 'local -'s still cause multiple entries to be added to the localvars list.
this problem will be addressed in a separate commit.

A tilde expansion generates a valid pathname. Splitting it using IFS
either leaves it unchanged or changes it to something unintended.
Example:
IFS=m HOME=/tmp; printf "%s\n" ~
