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.
