#compdef hub

# Zsh will source this file when attempting to autoload the "_hub" function,
# typically on the first attempt to complete the hub command.  We define two new
# setup helper routines (one for the zsh-distributed version, one for the
# git-distributed, bash-based version).  Then we redefine the "_hub" function to
# call "_git" after some other interception.
#
# This is pretty fragile, if you think about it.  Any number of implementation
# changes in the "_git" scripts could cause problems down the road.  It would be
# better if the stock git completions were just a bit more permissive about how
# it allowed third-party commands to be added.
