DataSource: if public-keys is a string, split it on newline

smoser · smoser · commit aa6726ebd6c8 · 2012-03-19T13:33:39.000-04:00
Previously, we were returning an array with a single item, which could
have contained newlines in it.

This does limit the potential content of a ssh public key, but it
seems unlikely that in the future a valid public key would contain a newline.
