#40 netstat -agn limits output to 10 chars with longer interface names
If any interface has a name longer than 10 characters, netstat -agn does not print out complete name.

Ok I just found out that my asumption that characters in interface names may only be alphabetical is wrong. I had no idea that interfaces with names like 'int-01?$:' are allowed(at least in Fedora). I will post a new patch shortly...
OK new patch. This should work.
i don't have IGMP on my system to double check, but the patch looks good, and the table is already set up to output to 15 cols. merged, thanks!
