See “imperative-mood” in `Documentation/SubmittingPatches`. Something like:

This adds a trailing space to the source which will make `ci/check-whitespace.sh` fail. I think you are supposed to do something similar to what is done in `t/t4124-apply-ws-rule.sh`. Namely to use some placeholder character like `_`:

    Acked-by:_

Together with:

    sed -e "s/_/ /g"

I could also imagine that a variable like `${SP}` might have worked together with `-EOF` similar to single quote:

   t/test-lib.sh:SQ=\'

But `t/test-lib.sh` does not seem to have that. (Although it does have `LF` (line feed)).
