Help Usage - Put Positional Arguments First

[jan-moravec]

Can we update the help for the positional arguments and put them to the front?

E.g. change:

Usage: apply [--help] [--version] [--serial VAR...] [--yes] INPUT

To:

Usage: apply INPUT [--help] [--version] [--serial VAR...] [--yes]

According to the current help the sample does not work if the list of serial numbers is used before the positional argument.

If we have optional argument with varying number of values, it should be called after the positional argument. Otherwise the optional argument might consume the positional one.

This issue is linked to #335
