Bug#86921: DPkg::Tools::Options::cmd::Version processing is broken

[Matt Zimmerman <mdz@debian.org>]

Package: apt
Version: 0.5.0
Severity: normal
Tags: patch

>From apt-pkg/deb/dpkgpm.cc:
      // Determine the protocol version
      string OptSec = Opts->Value;
      string::size_type Pos;
      if ((Pos = OptSec.find(' ')) == string::npos || Pos == 0)
         Pos = OptSec.length();
      else
         Pos--;

Those last two lines should be deleted (Pos will be the correct length of the
substring).  Currently, the code eats the last character before the space.
