sp. intuition. Maybe the double comma can be relieved with using ; for the first

[steveklabnik]

@bors r-

<stdin>:1:13: 1:15 error: character literal may only contain one codepoint: '❤
<stdin>:1 let heart = '❤️';

[steveklabnik]

When did that ignore go away? :(

[steveklabnik]

It is marked as ignore, and also, rustdoc --test src/libstd/lib.rs passes. So I dunno what's up here.

[apasel422]

@Manishearth Is there an issue filed for the bad span on that error message?

[steveklabnik]

Fixed a tidy error. Gonna wait and see what travis says before i re-approve though.

[Manishearth]

@apasel422 I do recall seeing some issue about emoji and stuff messing up spans before, but I don't remember what it was called. I'll look for it.

[apasel422]

@Manishearth For what it's worth, this also has a bad error message:

let x = 'ab';

error: character literal may only contain one codepoint: ';

[steveklabnik]

Travis hasn't passed, but a make check passed on my machine.

So it passes tests but not generation: #30032

[steveklabnik]

I've re-worded this so that it works now. I should start generating the docs as well as just running the doc tests :/
