(particularly notable is that "tmux neww\; splitw" would not split the
new window), and the few advantages do not make up for the confusion.
So drop this behaviour and return to using the current window and pane;

mark the source pane and then change to the target pane to run swapp or
joinp).
consistent but with much less duplication, but keeping the same internal
API. Also adds more readable aliases for some of the special tokens used
in targets (eg "{start}" instead of "^"). Some behaviours may have
changed, for example prefix matches now happen before fnmatch.
