--root-dir parameter needs space before assignment

[AvihayTsayeg]

Hi,
when using --root-dir= without space it return an error

lettuce --root-dir={feature dir}

Oops!
could not find features at ./features

but when adding space before the assignment it is working fine

lettuce --root-dir= {feature dir}

Regards, Avihay

Also, without an equal sign you also get the same error.
