Parsing fails due to new "Edition" field

[supermacro]

Hello,

Looks like the following commit prevents us from compiling cargo-watch on stable, since it adds a new field, that cannot be parsed on stable.

Here's a screenshot.

Any suggestions on how to fix this issue without us having to go over to nightly?

Thanks for the report! This crate now requires rustc 1.32.0+, so you'll want to update your rustc.
