Desktops and servers tend to have no power sensor, thus on_ac_power returns
255 ("unknown"). Thus, let's take any answer other than 1 ("battery") as
no contraindication to run gc.
If that tool returns "unknown", there's no point in querying other sources
as it already queried them, and is smarter than us (can handle multiple
adapters).

# An example hook script to verify if you are on battery, in case you
|
|
# are running Windows, Linux or OS X. Called by git-gc --auto with no
|
|
# arguments. The hook should exit with non-zero status after issuing an
|
|
# appropriate message if it wants to stop the auto repacking.
