That's fine, since the line limit is 100 chars now :-)

Ah! Is that in source code as well, or just docs?

Don't know if docs have the same restriction as source does, figured I'd mention it in case. |

…ip1995 cargo-ui tests: check that <dir>/src exists before processing test I forgot that I had fixed this in a PR I closed some days ago (rust-lang#5643). Before this change, cargo UI tests could fail when switching between branches if the previous branch had a test that the current branch does not have. The directory is not removed when switching because an ignored `Cargo.lock` file exists, and the code was trying to reach `$DIR/src` unconditionally. This change will just skip a directory that has no `src` subdirectory. changelog: none
