    Filter out backspace character in default man function output
    
    The man command can produce \b characters that are used to make
    argument bold. This lead to completions that looked like:
    
      ls -_--_-a_al_ll_l
    
    To fix this we need to use the col -b command to apply all of the
    backspaces in order and get the final column positions.
