9740cafdbd Automatically remove trailing whitespace from text files. (#527) r=rnewman
This was done using the following shell script:

```
find . -type f -not -path "*target*" \
       '(' -name '*.rs' -o -name '*.md' -o -name '*.toml' ')' -print0 | \
    xargs -0 sed -i '' -E 's/[[:space:]]*$//'
```

Which is admittedly imperfect, but manages to hit everything that was a problem in this repo.
