When I key in

[Order.java]$ jpa-new-field --named description <TAB>

, I do not get to see the options available for the command, until I key in a double-hyphen, like so:

[Order.java]$ jpa-new-field --named description --
--targetEntity  --type  --length  --lob  

I think a tying a TAB after a space should display the options for a command.

Note that this issue is limited in scope (and is different from FORGE-1554) to ensuring that parameter names are displayed as autocomplete options without requiring a -- to be keyed in by the user.
