[Bug Report] `:deleteTrailingSpaces` does not Work at EOF
@fox0430

When the spaces to be deleted are situated at the very end of the currently opened file, i.e., the last line, they are not going to be deleted.  This behaviour was found with a build of Moe from the latest repository state (`nimble install -y moe@#head`).

I consider this bug rather a low priority one as it does not break anything.  The command just does not work on the last line of a file.
