[PATCH] cli/show: list all filenames of a message in the formatted output

Instead of just having the first filename for the message, list all
duplicate filenames of the message as a list in the formatted
outputs. This bumps the format version to 3.

---

I presume the UI could do fancy things with this to highlight messages
with dupes better. I haven't quite figured out yet what that could be,
but this seems like the right thing to do regardless.
