die creates new warning on missing newline

Got this report via email:

Using Net::HTTP::Methods I very often receive errors:

Use of uninitialized value $line in concatenation (.) or string at /opt/perl5.28.2/lib/site_perl/5.28.2/Net/HTTP/Methods.pm line 534.
Use of uninitialized value $line in concatenation (.) or string at /opt/perl5.28.2/lib/site_perl/5.28.2/Net/HTTP/Methods.pm line 534.

            die "Missing newline after chunk data: '$line'"
                if !defined($line) || $line ne "";

When $line is undefined it tried to print it in die statement.

Start in Net/HTTP/Methods.pm around line 534, where the missing-newline error is reported and the undefined $line value is interpolated. Reproduce or inspect that path and verify the missing-newline case no longer emits an uninitialized-value warning while still reporting the error.
