Bug#457741: zsh-doc: Fails to configure

[Sven Joachim <svenjoac@gmx.de>]

Package: zsh-doc
Version: 4.3.4-dev-6-3
Severity: serious

The postinst of your package fails:

,----
| Setting up zsh-doc (4.3.4-dev-6-3) ...
| install-info(/usr/share/info/zsh.info.gz): warning, ignoring confusing INFO-DIR-ENTRY in file.
| 
| No `START-INFO-DIR-ENTRY' and no `This file documents'.
| install-info(/usr/share/info/zsh.info.gz): unable to determine description for `dir' entry - giving up
| dpkg: error processing zsh-doc (--configure):
|  subprocess post-installation script returned error exit status 1
| Errors were encountered while processing:
|  zsh-doc
`----

This is the header of /usr/share/info/zsh.info.gz:

,----
| This is zsh.info, produced by makeinfo version 4.11 from tzsh.texi.
| 
| INFO-DIR-SECTION Utilities
| START-INFO-DIR-ENTRY
|      * ZSH: (zsh).                     The Z Shell Manual.
| END-INFO-DIR-ENTRY
`----

And here is the header of /usr/share/info/zsh.info.gz in the working
4.3.4-dev-6-1 version:

,----
| This is zsh.info, produced by makeinfo version 4.11 from tzsh.texi.
| 
| INFO-DIR-SECTION Utilities
| START-INFO-DIR-ENTRY
| * ZSH: (zsh).                     The Z Shell Manual.
| END-INFO-DIR-ENTRY
`----

I have CC'ed the texinfo maintainer, there is likely something wrong
with the latest fix for #451268.
