With additional prefixed flags for authfiles, it is possible to override the shared authfile flag to use different authfiles for src and dest registries. This is an important feature if the two registries have the same domain (but different paths) and require separate credentials.
Closes#773.

/skopeo.1 was a generated file before #35; now this path is not used
(replaced by man1/skopeo.1); if the generated file is left around, it is
obsolete (and confusingly empty). Remove it from .gitignore to nudge
developers like me to clean up.
