Steps to reproduce:

1. Have command with a required option argument with a short name (e.g -a).
2. Have command with a required option argument with a short name (e.g -bc).
   Run the command with the option argument but with no space after the argument name (e.g commandname -asdf).
   Run the command with the option argument but with no space after the argument name (e.g commandname -bcd).

Actual result:

1. Command runs and option argument -a has value "sdf".
2. error: unknown option '-bcd'

Can short option with single character report the same error like issue 2?
