This release updates the integrated TAB-completion, such that running completion for the help sub-command will only show valid subcommands.
For example:
$ aws-utils help wh[TAB]
whitelist-self whoami Because we can be used for a lot of purposes our tab-completion is a bit inflexible, it completes the name of a valid sub-command, then files/directories. That's probably the best we can do without forcing users to define the kinds of completion they want - but completing on sub-commands is a trivial improvement which is worth making regardless.
