Panagiotis Astithas c54c7b376d hooks/pre-auto-gc: adjust power checking for newer OS X
The output of "pmset -g batt" changed at some point from "Currently
drawing from 'AC Power'" to the slightly different "Now drawing from
'AC Power'". Starting the match from "drawing" makes the check work
in both old and new versions of OS X.

# An example hook script to verify if you are on battery, in case you
# are running 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.
#
# This hook is stored in the contrib/hooks directory. Your distribution
# may have put this somewhere else. If you want to use this hook, you
# should make this script executable then link to it in the repository
# you would like to use it in.
#
# For example, if the hook is stored in
# /usr/share/git-core/contrib/hooks/pre-auto-gc-battery:
#
# cd /path/to/your/repository.git
# ln -sf /usr/share/git-core/contrib/hooks/pre-auto-gc-battery \
# hooks/pre-auto-gc
