Do not put a space between status-left/status-right and the window list,
instead move the space into the defaults for the options (so status-left
now defaults to "[#S] ". From Balazs Kezes.
Tidy up mode-mouse check.
Add V for select line with vi(1) keys. From Juho Pohjala.
Wrap when copy mode is used for output, from Balazs Kezes.
V should be vi not emacs, also sort. From Theo Buehler.
Empty strings should be false too for #{?}, from Marc Finet.
Two improvements to reflow from Balazs Kezes:

- Don't extend the line to full width on insert/delete character which
  means leaves extra spaces when reflowing.

- Only mark a line wrapped when the cursor actually goes off the end,
  not on newlines which can be used for positioning.
