The unstable-feature attribute requires an issue (neglecting it is E0547), which gets used in the error messages. Unfortunately, there are some cases where "0" is apparently used a placeholder where no issue exists, directing the user to see the (nonexistent) issue #0. (It would have been better to either let `issue` be optional—compare to how issue is an `Option<u32>` in the feature-gate declarations in libsyntax/feature-gate.rs—or actually require that an issue be created.) Rather than endeavoring to change how `#[unstable]` works at this time (given competing contributor and reviewer priorities), this simple patch proposes the less-ambitious solution of just not adding the "(see issue)" note when the number is zero. Resolves rust-lang#49983.

I mentioned this in #41260 and @GuillaumeGomez was against it at the time. Not sure how people feel about this, although I personally would prefer this. |
|
Optional related issue sounds good for me. |

r? @nikomatsakis for re-assignment or nomination. Not sure how contentious this is. |

Lets have a follow up PR making the related issue optional, but for now this is a net positive. |
