[Pkg-zsh-devel] Bug#768937: zsh: [patch] not binNMU-safe due to --link-doc between arch-dep and arch-indep

[Simon McVittie]

Package: zsh
Version: 5.0.7-3.1+b1
Severity: serious
Tags: patch
Justification: uninstallable

As noted on #747141, it is not safe for dh_installdocs --link-doc to
link together the documentation directories of an architecture-dependent
package and an architecture-independent package, because the resulting
lockstep dependency is unsatisfiable after the architecture-dependent
package receives a binNMU.

Here's a patch to fix that, using the approach that Axel Beckert
described on that bug:

I changed zsh-dbg from "docs linked to zsh-common" to "docs linked to zsh",
and installed the bare minimum of Policy-required docs in zsh.
zsh-dev is now self-contained (I don't think it's worth optimizing
its size).

I put the dpkg-maintscript glue to migrate /usr/share/doc/zsh from a
directory to a symlink in both zsh and zsh-common, because both packages
ship files in that directory now, and either package might be unpacked first.
