[pkg-netfilter-team] Bug#1043351: ebtables: unescaped hyphens in manpage

[Linus Lüssing]

Package: ebtables
Version: 2.0.11-5
Severity: normal
X-Debbugs-Cc: linus.luessing at c0d3.blue

Dear Maintainer,

I tried running the following ebtables command, but got an error:

```
$ sudo ebtables -I INPUT -i veth1 -j mark ‐‐mark-set 0x42
ebtables v1.8.9 (nf_tables): Bad argument : '‐‐mark-set'
```

On #netfilter IRC people with eagle-eyes and apparently a different font
than me pointed out that I was trying to use Unicode instead of ASCII
hyphens. Changing the command to use "--mark-set", with ASCII hyphens,
instead helped.

It seems I copied the Unicode version from the ebtables manpage. I believe
it's a similar issue to this one:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1043309

That is un-escaped hyphens in the manpage source code are rendered to
Unicode hyphens.

To fix this the hyphens should be escaped in the manpage source code.

Regards, Linus

(Kudos to @aiyion at infosec.exchange on Mastodon who pointed me to the
curl Debian bug report and by that to the origin of my issue.)
