* Initial support for scroll history. = to enter scrolling mode, and then
vi keys or up/down/pgup/pgdown to navigate. Q to exit. No horizontal history
yet (need per-line sizes) and a few kinks to be worked out (resizing while in
history mode will probably cause trouble).

* Fix format string error with "must specify a client" message. Also

- session specification is all over the place. some things use -s before cmd,
some -s after, some no -s, there are various uses of -n. the differences are
sort of logical, but confusing. needs rethought
- XXX should -i for win idx be before cmd too??
- bind non prefix keys (useful for shift-pageup for scrollback, when we
have scrollback)
- for scrollback (?) or copy/paste, modal key/display handling (key/draw
through function pointers in screen). also move ? etc to that too
- stuff like rename would be nice to be able to do in-client like screen, if
it could be implemented in a non-icky way
- there is to much redrawing. use flags? (there was a problem with this idea..?)
