A bar must be full-screen-width (or height, for vertical bars) to
have an "exclusive zone", otherwise it appears on top of other windows
instead of moving them out of the way. To right-justify (or bottom-
justify) the indicators in a bar, add :gravity :end to its options
Am *probably* going to get rid of this again, in favour of adding
support for "spacers" in the bar - then the same bar could contain
both left- and right-justified indicators
- currently shows ssid and signal strength, if wlan
- for lan, should show interface name (not tested)
plan to enhance with
