Friedrich Clausen updated CLI-297:
----------------------------------
    Description: 
When an option taking an argument is specified with a space the blank checking 
works:
{code:none}
$ CheckEmpty --widget-count
org.apache.commons.cli.MissingArgumentException: Missing argument for option: 
widget-count
{code}
 However when using the equals sign as a separator that checking does not seem 
to apply
{code:none}
$ CheckEmpty --widget-count=
Received widget count of:
{code}
I'd expect it to throw an exception just like the space separated variety.
