satellite: use double-dash to disambiguate refspec and pathspec
Created by: davvid
When a file or directory is named the same as either the source or target branch then git will fail to diff because of the ambiguity. e.g. if you touch a file called "master" you will see this output:
$ git diff HEAD master
fatal: ambiguous argument 'master': both revision and filename
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'The solution is to use the double-dash to separate paths from revisions, as git suggests in its error message.
