Support "bracketed paste" mode. This adds a -p flag to paste-buffer - if
this is used and the application has requested bracketed pastes, then
tmux surrounds the pasted text by \033[200~ and \033[201~. Applications
like vim can (apparently) use this to avoid, for example, indenting the
text. From Ailin Nemui.
Terminate strftime buffer properly and free format string, whoops. From
Tiago Cunha.
Add A and I keys for vi status line editing.
Accept hex values as keys, needed for send-keys, based on a diff from
