Usage: gcm your message (no quoting of the commit message needed)
Source: https://rawgit.com/rsp/scripts/master/gcm
Runs: git commit message -m ...
The commit message is composed from all command line arguments (you don't have to quote them).
So running: gcm your message
is equivalent to: git commit -m "your message"
