added basic filtering of non-repeatable backspaces. Working better, but still has problems with auto-inserted matching braces, since extra cursor motions are involved
added filtering to repeat command to handle matching braces
realized that the mix of faulty patterns can be repeated in a single edit, and thus the filtering must be repeated until it fails
