Pattern: Trailing whitespace
Issue: -
Adding trailing whitespace can cause extra work for others editing the same file, when they merge, as can removing existing trailing whitespace. So: Don't introduce trailing whitespace. Remove it if you're already changing that line, or do it in a separate clean-up operation (preferably when no-one else is working on the file).

With
trailing-spaces: {}
the following code snippet would PASS:
this document doesn't contain any trailing spaces
the following code snippet would FAIL:
this document contains trailing spaces on lines 1 and 3
