Handling of space characters in option values

Using spaces in option values can have unexpected effects when parsed with CommandLineParser, for example;

--name joe bloggs

Correctly gives a value for the name option of "joe". However;

--name joe\ bloggs

Gives the value "joe\ bloggs" - I would expect it to give the value "joe bloggs". Furthermore;

--name 'joe bloggs'

Gives a value of "'joe", and similarly;

--name "joe bloggs" gives a value of ""joe"
