Merge branch 'cb/cherry-pick-rev-path-confusion'

The command line parser choked "git cherry-pick $name" when $name can be
both revision name and a pathname, even though $name can never be a path
in the context of the command.

The issue the patch addresses is real, but the way it is implemented felt
unnecessarily invasive a bit.  It may be cleaner for this caller to add
the "--" to the end of the argv_array it passes to setup_revisions().
