Previously 'set -ql' would only look for variables in the immediate local scope. This was not very useful. It's also arguably surprising, since a 'set -l' in a function, followed by a 'set -ql' in a child block, would fail. There was also no way to check for a function-scoped variable, since omitting the scope would also pull in global variables. We could revisit this and introduce an explicit function scope. Fixes #2502
