failing test case for #115 [rt.cpan.org #84767]

need to modify warn/dir in CGI::Carp to output the last filehandle
read and the line number. $. is for the later, and with perl5.18 we
can use a special perlvar to get the last read filehandle, but need
to make this back compatible so may need to grok the perl source to
find out what it does for die/warn
Merge branch 'master' into rt/84767
resolve #115 [rt.cpan.org #84767] - die with line

actually nothing to do here, seems to work ok.
