Relative path to deleted file is not working

[carlolars]

Relative paths to files check if the file exist on the file system to determine if it is a path and not a RegEx. This is of course not working for deleted files, eg git checkout -- deleted\file.txt.

-- could be used to detect if the following arguments are paths, but the use of -- is not mandatory. Maybe it will work in most cases? (And is -- only used before paths???)
