rust: fix non-utf8 char in requirements.rs Apparently Phabricator detect `rust/hg-core/src/requirements.rs` file as non utf8 ‽, and mark it as binary. During application it ended up being non-utf8 and this made Rust (and as a result heptapod) very angry:: error: couldn't read hg-core/src/requirements.rs: stream did not contain valid UTF-8 --> hg-core/src/lib.rs:11:9 | 11 | pub mod requirements; | ^^^^^^^^^^^^ error: aborting due to previous error error: could not compile `hg-core`. The after "fixing", the file content has no character matching the following regexp: [^0-9-a-zA-Z /(|).,{}!\[\]:"&=>?_*-;<`'#] So we should be fine, unless Phabricator does something funny again.
