Fix a regression where the WM_CHECKQUEUE message was posted to the wrong HWND.
The timers still worked but the execution of the events was delayed to the point where programs didn't work correctly.
Rather than duplicate the correct logic, I made CMainFrame->PostCheckQueueMessage() public.
Having it be private contributed to this regression.

Strip trailing whitespace

Add a test case for when the array origin's number isn't given {1 2}@
Also add some comments and TRACEINSTRUCTION.

Add some mismatched curly brace tests to RUNPARSE.

Cleanup: Remove a local variable that wasn't used (vestige from an earlier refactoring)

Add/correct comments in runparse_node.

Update some of the expected values after reverting the change for bug #589 that removed minus to negative remapping from runparse_node.
Now a space before a minus sign with no space after always indicates negation.

Add some more test variations for RUNPARSE, particularly for its handling of the shebang line

Add a comment

Undo the part of the fix for Bug #589 that removed the special handling of - from runparse_node.
This was necessary to make "SUM 1 -1" run; without it, it's "SUM (DIFFERENCE 1 1)" and is missing an input.
