Bug#1040197: elpa-ghub: Fails to upgrade from 3.5.6-1 to 3.6.0-2 due to dropped but still required dependency on elpa-treepy

[Axel Beckert <abe@debian.org>]

Package: elpa-ghub
Version: 3.6.0-2
Severity: serious

Hi,

somewhere between elpa-ghub 3.5.6-1 and 3.6.0-2, it dropped the
dependency on elpa-treepy despite it still seems necessary.

It might be that this was some automatic thing as this change was not
mentioned in debian/changelog.

Here's a summary of the upgrade failure:
