Bug#82660: libapt-pkg-dev likely typo in algorithms.cc

[Carl Christofferson <cchris@cchris.seanet.com>]

Package: libapt-pkg-dev
Version: 0.3.19

I believe that in algorithms.cc on line 320 the string
  "APT::Ingore-Hold"
was intended to be
  "APT::Ignore-Hold"

The manual page refers to APT::Ignore as does other source code (see
below).

I have no indication that this causes a problem but it might be relate
to bug #78042.

A search of the apt-0.3.19 source yields more instances of the spelling
"Ingore":

bash-2.04$ grep 'APT::Ingore' $(find apt-0.3.19 -name '*.cc' -print)
apt-0.3.19/apt-pkg/algorithms.cc:      if
(_config->FindB("APT::Ingore-Hold",false) == false)
apt-0.3.19/cmdline/apt-get.cc:      if
(_config->FindB("APT::Ingore-Hold",false) == false)
apt-0.3.19/cmdline/apt-get.cc:     
{0,"ignore-hold","APT::Ingore-Hold",0},      
apt-0.3.19/debian/cvs-build/apt-0.3.19/apt-pkg/algorithms.cc:      if
(_config->FindB("APT::Ingore-Hold",false) == false)
apt-0.3.19/debian/cvs-build/apt-0.3.19/cmdline/apt-get.cc:      if
(_config->FindB("APT::Ingore-Hold",false) == false)
apt-0.3.19/debian/cvs-build/apt-0.3.19/cmdline/apt-get.cc:     
{0,"ignore-hold","APT::Ingore-Hold",0},      

And a few instances of the spelling "Ignore"

bash-2.04$ grep 'APT::Ignore' $(find apt-0.3.19 -name '*.cc' -print)
apt-0.3.19/apt-pkg/algorithms.cc:   if
(_config->FindB("APT::Ignore-Hold",false) == false)
apt-0.3.19/debian/cvs-build/apt-0.3.19/apt-pkg/algorithms.cc:   if
(_config->FindB("APT::Ignore-Hold",false) == false)
