Bug#555320: checks manpages with -E UTF-8, but does not inform about this

[Evgeni Golov <evgeni@debian.org>]

Package: lintian
Version: 2.2.17
Severity: minor

Hi,

I was just checking one of my packages and got the following warning:

W: thinkfan: manpage-has-errors-from-man usr/share/man/man1/thinkfan.1.gz  Invalid or incomplete multibyte or wide character
N: 
N:    This man page provokes warnings or errors from man.
....
N:    To test this for yourself you can use the following command:
N:     LANG=C MANWIDTH=80 man --warnings -l manpage-file >/dev/null

Running the command showed exactly zero warnings from man.
Looking at /usr/share/lintian/checks/manpages, it reads:
        my $cmd;
        if ($file =~ m,^(.*)/(man\d/.*)$,) {
            $cmd = "cd unpacked/\Q$1\E && man --warnings -E UTF-8 -l \Q$2\E";
        } else {
            $cmd = "man --warnings -E UTF-8 -l unpacked/\Q$file\E";
        }
(and it sets LANG to C some lines later)

so either the description misses -E UTF-8, or the check is wrong :)
You should know better what is meant here, I'm far from a man expert.

Thanks for your work
Evgeni
