Jon Gjengset 88948e0ee3 Include span label in rust lints (#601)
* Include span label in rust lints

This turns relatively unhelpful error messages like

    mismatched types

into more expressive messages along the lines of

    mismatched types: expected bool, found integral variable

Fixes #597.

* Exclude rust lint span label if empty

* Use single-quoted strings in vimscript

* Add test for detailed rust errors

* Prune Cargo JSON

* Use matching error file name

* Byte offsets not char offsets
