@eliasow, I see you have added me as a reviewer, but you haven't assigned the PR to me. Hm, perhaps you mean that the PR isn't ready for review yet? More likely you forgot to assign me... I'll wait to be assigned before reviewing.

A PR should always be assigned to whoever is currently responsible for taking action (develop, review, test, whatever). The only time a PR should be unassigned is if the responsible party has departed and abandoned the PR, and there is no one else to assign it to.

GitHub indicates that the file doesn't end in a newline:

Modern unix programs are often smart about it, but old-fashioned programs still read input line by line and detect each line by virtue of it ending in a newline^* such that if the last line of the file doesn't end in a newline, it is ignored. For safety's sake, make sure the file ends in a newline. The Infolab has set up Emacs to add a final newline when saving a file, if there isn't one already. Perhaps your editing environment has a similar option.

^* where "newline" means the appropriate CRLF character(s) for the operating system

LGTM, but for future reference, a better commit message would have been "Add newline at end of file".
