Hi Mark,

Thanks for contributing this patch!

I know from a conversation we had in IRC that you needed this feature to
track down a bug you were hitting. Thanks for going the extra mile to
write a new test case and a complete patch for the new feature.

I think the only thing I would like to see in addition is an update to
the documentation to make it explicit that --output=3Dfiles will emit all
filenames for a message that has more than one filename.

It's amazing how painful it is to get the corner cases right here, isn't
it? It's almost enough to make me wish that we allowed trailing
separators as a standard element of style in conventional prose. [*]

[*] Though if I had that wish, I'd also want to wish for the abolition
of any distinction for singular and plural nouns. The code to generate
messages like the following is a pain to write:

	Processed 1 file in almost no time.
	Added 1 new message to the database. Removed 1 message.

(And that's without even adding support for translations which would
further complicate this.) Ah, well, the price we pay to make code with
clean output.
