Bug#280824: vim-doc: Preinst script is broken

[Kevin McCarty]

Package: vim-doc
Version: 1:6.3-031+1
Severity: grave
Justification: renders package unusable

Hi,

Trying to install the latest version of vim-doc causes a long set of error
messages to be printed out:

# dpkg -i /var/cache/apt/archives/vim-doc_1%3a6.3-031+1_all.deb
(Reading database ... 96101 files and directories currently installed.)
Preparing to replace vim-doc 1:6.3-013+2 (using .../vim-doc_1%3a6.3-031+1_all.deb) ...
rm: cannot remove `/usr/share/doc//Debian': Is a directory
rm: cannot remove `/usr/share/doc//FAQ': Is a directory
rm: cannot remove `/usr/share/doc//HOWTO': Is a directory

rm: cannot remove `/usr/share/doc//zsh-doc': Is a directory
dpkg: error processing /var/cache/apt/archives/vim-doc_1%3a6.3-031+1_all.deb (--install):
 subprocess pre-installation script returned error exit status 1

The problem appears to be an undefined variable "$pkg" in the preinst.
I guess $pkg is supposed to be vim-doc?  Good thing you didn't use rm -r,
that would really have been a pain to fix :-P

#! /bin/sh -e

if [ ! -h /usr/share/doc/$pkg ] ; then
  if [ -d /usr/share/doc/$pkg ] ; then
    rm -f /usr/share/doc/$pkg/*
    rmdir /usr/share/doc/$pkg/
  fi
fi
