@evanmiller: how do you generate this file? No matter which options I pass to ragel, it uses different formatting, and even different logic. Or do you re-format the code manually?

Could be an older or newer version of Ragel. What version are you using?

I have 7.0.0.12 (that's what Fedora has in its repo). What about you?

Ah, yeah Ragel 7 uses a completely new architecture based on Colm. I've been using 6.x. I don't mind either way as long as we standardize.

Got it. Then I'll send out a separate PR that just re-generates this file using 7.x - and then this PR will look more reasonable.
An empty zip file is completely valid, but the current mod_zip syntax does not support them. This comes up in cases where e.g. a user clicks "Download this folder" - and the backend needs to special-case empty folders and use different code to generate an empty .zip file. This is technically a breaking change - though the documentation does not say anything about trailing line breaks, and it seems unlikely that anyone would actually rely on the last line break being optional.
