Platform_is fix needed?

Hi,

system_spec.rb fails all its tests because the before(:each) calls
platform_is(:windows) without a block, while it appears to require
one.

Can I just fix this specific spec by using platform_is +
platform_is_not instead, or is it better to fix platform_is to allow
calls without blocks ? I’d prefer the former because it sounds
simpler.

what do you think ?
