Since you're already changing things, it might look better when given two suggestions with different help messages.

e.g.

span_suggestion(..., "either convert it to it's owned type", ...)
span_suggestion(..., "or clone it", ...)

[kartva]

Thanks for the suggestion! I initially wasn't sure about using the method, but this looks much better.

[Jarcho]

That is nicer to read.

Thank you for the fix. @bors r+
