[IMPROVE] '-' arguments with more than one letter

[montezdesousa]

@deeleeramone noted this: "If I am remembering correctly, there was a previous effort to clean up all arguments, terminal-wide, so that - are assigned to only single letters; and arguments which can't reasonably be abbreviated as one letter should convert to being only -- with the full argument name. I'm pretty sure there was a specific reason for this, argparse-related, but it was a little while back."

Yes! The reasoning is that if I have something that is -ab it actually treats it as -a -b which can be problematic.
