Bug#766737: lintian: No more cares about ~/.lintianrc

[Axel Beckert <abe@debian.org>]

Package: lintian
Version: 2.5.29
Severity: serious

Hi,

Since 2.5.29 my ~/.lintianrc is ignored unless I used "--cfg
~/.lintianrc". Culprit is the new environment cleaning which cleans out
$ENV{HOME}, too:

Watchpoint 0:   $ENV{'HOME'} changed:
    old value:  '/home/abe'
    new value:  ''
Lintian::Internal::FrontendUtil::sanitize_environment(/usr/share/perl5/Lintian/Internal/FrontendUtil.pm:60):
60:                 delete $ENV{$key}
61:                   if not exists($PRESERVE_ENV{$key})
62:                   and $key !~ m/^LINTIAN_/;

I haven't checked for the XDG based variants, but that likely should be
cross-checked, too.
