imp(Positional Arguments): now displays value name if appropriate
f0a9991 
When value names are use, they will be displayed in help and error
messages instead of the argument name. For example, an argument named
`arg` but with the value name `FILE` will be displayed as `[FILE]`.
Likewise multiple value names will be displayed properly such as `[FILE1] [FILE2]`

Closes #420
