Why are you removing this line? It seems to be not unrelated to the new -e options.

This is true but IMHO shell tools are expected to emit their usage either when called without arguments or when called with an explicit –h or –help option. One of those should work and is not an error. It is just the user asking for advice how to use the tool. YMMV.

Here you should write -e|--edit to also show the long-option alias.

You should pre-initialize the variable edit beforehand similar to what is done for the other options.

Not all $EDITORs might support editing a directory .. This then would fail here...

Correct. The user is free to either provide a capable editor in $EDITOR or to explicitely name the file he or she wants to edit. If they refuse to provide the prereqs they won’t receive the benefits. That's something to be documented but I would not miss the fine feature of directory selection as most editors in use today (and preinstalled) can do it.

It's OK to print the number of actually provided arguments, but (a) it doesn't read nicely when you see "invalid number of arguments 7" and (b) the actual number of expected arguments could be more useful in the output. Perhaps a better error could be "invalid number of arguments (expected 1 argument, received N arguments)".
