Sensible git submodules

.bashrc

# make git submodules usable
#   This overwrites the 'git' command with modifications where necessary, and
#   calls the original otherwise
git() {
    if [[ $@ == clone* ]]; then
        gitargs=$(echo "$@" | cut -c6-)
        command git clone --recursive $gitargs
    elif [[ $@ == pull* ]]; then
        command git "$@" && git submodule update --init --recursive
    elif [[ $@ == checkout* ]]; then
        command git "$@" && git submodule update --init --recursive
    else
        command git "$@"
    fi
}

Add this code to your .bashrc file to automatically handle git submodules

This has unintended behavior if you're trying to just revert working copy modifications to a single file e.g.

git checkout -- dw1000.c

This proceeds to revert any commits in submodules which haven't been committed to the parent repository. Any ideas on how to fix this behavior?
