update usage for eval

[ehazlett]

@hairyhenderson mentioned issues with using quotes around eval for loading the environment. This updates the usage info after the create command to remove the quotes.

Hang on- @tianon had quotes on it in #795 . Do we have a specific reproducible use case where we know this is an issue?

[tianon]

Quotes are definitely important for proper whitespace preservation, but I can't think of any current common issues with either way.

[nathanleclaire]

OK - if we aren't aware of any issues with the status quo then I'm all for removing the quotes today. Should keep it in mind in the future though.

[nathanleclaire]

I think there are some docs that will need to be updated with this too.

[ehazlett]

@hairyhenderson can you provide some feedback for this?

#869 looks related too.

[tianon]

@nathanleclaire well hold up; if there aren't concrete problems removing them fixes, why remove them? They're definitely more "correct", AFAIK.

[ehazlett]

Ok I'm going to close this one. I can't get any issue re-produced.

@hairyhenderson if you run into the issue again, can you file an issue with details on how to reproduce?

thanks all -- sorry for the noise.
