rev-parse: fix --resolve-git-dir argument handlingjk/rev-parse-resolve-git-dir

There are two problems here:

1) If no argument is provided, then the command segfaults
2) The argument is not consumed, so there will be excess output

Fix both of these in one go by restructuring the handler for this
option.
