slightly more helpful help, if it's helpful

[mong8se]

I know the idea is to be lightweight as possible, but here is a slightly more helpful help, if it's helpful for anybody.

It omits the help and default tasks from the list of commands, and then displays the contents of the default task:

function help {
  echo "$0 <task> <args>"
  echo "Tasks:"
  compgen -A function | grep -v 'help\|default' | cat -n
  echo
  type default | sed -e '1d; 2s/()/task:/; s/^/    /'
  echo
}

The output looks like this, for an example Taskfile with a slightly complicated default for illustration:

./Taskfile <task> <args>
Tasks:
     1	install
     2	build
     3	run
     4	update
     5	upgrade

    default task: 
    { 
        update;
        for file in src/*;
        do
            upgrade $file;
        done
    }

Task completed in 0m0.003s

FWIW, here is my take on improving the help text: https://gist.github.com/gggeek/a836fa51229d31985fe67515d6c3d7e4

The changes are:

• allow each task to have a description besides a name
• the task description is parsed from comments in the script source

PS: lol, I just found out a very similar solution to my one was already proposed in issue #4
