Clean up some uses of showStart with "" for the file, or in some cases, a non-filename description string. That would generate bad json, although none of the commands doing that supported --json. Using "" for the file resulted in output like "foo rest"; now the extra space is eliminated. This commit was sponsored by Fernando Jimenez on Patreon.
