fix lines/cols, was swapped !
implement sequence-aware functions

rjust, ljust, center, textwrap, with accompaning test cases.

This differs from my previous implementation in that sequences are
entirely implemented by regular expressions.

keyboard support depends upon these functions and must branch from here.

Additional test cases must be created to test the completeness of the
regular expressions. Right now we're only testing the obvious, and not
so much all the non-obvious. The re patterns were heavily commented to
help identify them.
include a failed test, working on it ..
