Bug#880804: debci: please make the build reproducible

[Chris Lamb]

Source: debci
Version: 1.7.1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: fileordering

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that debci could not be built reproducibly.

This is because the documentation generation depends on (non-
determinstic) filesystem ordering.

Patch attached.
