Subject: Add extra tests and changes for config_from file.
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=config_from_file_cli;p=gitmo%2FMooseX-Getopt.git

Add extra tests and changes for config_from file.

These are all from Alex Bowley.
At the moment I'm unsure if I'm happy about the tests changes as we're
throwing different error messages. I think those are likely to break
someone's code - if that's unavoidable then so be it, but I'd like to
see if we can convince the original error message back
