## Continuum status in tmux status line

There is an option to display current status of tmux continuum in tmux status
line. This is done via `#{continuum_status}` interpolation and it works with
both `status-right` and `status-left` tmux native options.

Example usage:

    set -g status-right 'Continuum status: #{continuum_status}'

When running, `#{continuum_status}` will show continuum save interval:

    Continuum status: 15

or if continuous saving is disabled:

    Continuum status: off
