VIM and [Python] block jumping

[C. Laurence Gonsalves]

Of course, right after I posted that, realized that there's a problem.
The blockMotion function doesn't account for lines that are
continuations of other lines. That means that triple-quoted string
literals, lines with more {[('s that }])'s, and lines joined with \ can
screw it up. Are there any other situations? I'll try to post a
corrected version later. Some of those problems are pretty nasty though
(triple-quoted strings in particular).
