Fix indentation
Ensure not to call `tmux` when running specs.
Fixs notifier when display_on_all_clients is true

line 254 no spaces '\#{client_tty}' are important
Remove null terminal from clients list

Starting tmux in control mode ```tmux -C``` results in (null) being
listed in client list ```tmux list-clients -F '#{client_tty}'```
Update README.md

R.I.P @netzpirat
correctly match notification type to urgency argument in notifysend
notifier
Fix tmux <= 1.6 quiet option.

Sections of guard pass -q to tmux, which is an option added in tmux 1.7.
This option is now inserted by the _quiet_option function, which is
dependent upon the tmux version.

Fix tmux <= 1.6 quiet option.
Merge pull request #583 from mrloop/tmux_notifier_fix

Fixes tmux notifier when display_on_all_clients is true
use rspec local + guard-rspec failed_mode
fix occasionally failing tmux spec
move guardfile reevaluation to runner (refactor)
mark interrupted task as failed (fixes #582)

Previously, an Interrupt resulted in a plugin being fired.
Respond to signals using threads (fixes #571)

  * Thread necessary because Lumberjack uses lock

  * Also, Listen has bug where pause calls Record.build
  (instead of Record.async.build)

  * join should not be used due to potential deadlocking

  * run within preserved state to avoid overwriting Pry
Prevent Pry restarting when unwatched files change

  * closes #536 even thought it only mitigates the problem (the
  "correct" fix is synchronous guard: #595, where Pry.start
  doesn't have to be reentrant any more)

  * also saves the user from adding various ignore rules to
  make polling work better, etc.

  * this also prepares Guard for better integration with
  upcoming Listen 3.x API
