ael

closes issue #10834 ; where a null input to a switch statement results in a hangup; since switch is implemented with extensions, and the default case is implemented with a '.', and the '.' matches 1 or more remaining characters, the case where 0 characters exist isn't matched, and the extension isn't matched, and the goto fails, and a hangup occurs. Now, when a default case is generated, it also generates a single fixed extension that will match a null input. That extension just does a goto to the default extension for that switch. I played with an alternate solution, where I just tack an extra char onto all the patterns and the goto, but not the default case's pattern. Then even a null input will still have at least one char in it. But it made me nervous, having that extra char in , even if that's a pretty secret and low-level issue.

pbx_ael.c

closes issue #10870 ; where a CUT() function call in a switch expr doesn't execute correctly, because the commas in the function args are not converted to vertbars before the func is called. I modified just the switch code to convert the commas to vertbars if there, but if more of these sort of probs are found, I may have to resort to something a little more fundamental. We'll see, I guess.
