Add '-h' as alias for '--help' on all commands
As a new BuildStream user, I reach for the help often. --help
is more typing than I expected.
I tested this by running all the bst subcommands with -h
before and after the change. No subcommands are using -h
for anything else, all commands succeeded with the new help option.
Click has supported such overriding since version 2.0, as documented: http://click.pocoo.org/5/documentation/#help-parameter-customization
Click 2.0 was released in 2014.
