新規にブランチを作成したら自動で空コミットを作成するgit hook

post-checkout

#!/usr/bin/env ruby

before, after, switch = ARGV
exit 0 unless before == after
exit 0 unless switch.to_i == 1

branch = `git rev-parse --abbrev-ref HEAD`
msg = "Created new branch #{branch}"
system(%(git commit --allow-empty -m "#{msg}"))

Correct quote wrap problem for commit massage.
