[EXPAND] Move parse-time quote flag detection to run-time
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:
<>
