Jeff King bafed0dfb4 t9902: add completion tests for "odd" filenames
We correctly handle completion items with spaces just fine,
since we pass the lists around with newline delimiters.
However, we do not handle filenames with shell
metacharacters, as "compgen -W" performs expansion on the
list we give it.
