[Reproducible-builds] Bug#782462: txt2man: does not build reproducibly

[Jonathan Wiltshire]

Package: txt2man
Version: 1.5.5-2
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps

txt2man embeds a timestamp in its own manuals which is, by default, the current
date. This makes builds deterministic.

The attached patch parses debian/changelog to find the date of the current
package version and passes that to the call to txt2man instead.

For hopefully obvious reasons this is not suitable for inclusion upstream since
it relies on dpkg-parsechangelog.
