Tab display can be toggled on or off with `Ctrl+Shift+T`. The toggling
takes place per-window and not globally, so we can have a wezterm
terminal on desktop 1 with a tabbar and on desktop 2 without. Opening
a new terminal always defaults to an enabled tab bar.
When copying the recent buffer into an editor for copying/editing/doing
whatever with, we should copy *logical* lines since that is generally
what we want to be working with instead of arbitrary line-breaks.
Wezterm helpfully provides us this possibility (thanks, Wez!).
