Subject: Handle the emacs-{gtk,lucid,nox} doc dir transition manually
X-Git-Tag: archive/raspbian/1%29.2+1-2+rpi1~1^2~193
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=c60e9080df0d924d6a45e77725c11959926f24a7;p=emacs.git

Handle the emacs-{gtk,lucid,nox} doc dir transition manually

Before the unversioning, these packages were in a different source
package (emacs-defaults) and were arch all.  Since
dpkg-mainscript-helper can't hande "all to any" transitions
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=813455), clean up
manually in the preinsts.

Thanks to Sven Joachim for reporting the problem and indentifying the
underlying cause.

Closes: 905555
