With a single -v option, there was no change in how many ignorable ports
(e.g. closed or filtered) would be shown before being rolled up into the
"Not shown" line. Taking verbosity plus 1, we now get up to 50 ports in
an ignorable state, versus up to 25 without -v.
PortList::forgetPort in verbose mode tries to print details on a Port
after it has been deleted. This function is only called in idle and ftp
bounce scans. Reported by Mak Kolybabi:

for file in `grep "* including the terms and conditions of this license text as well. \*" * -r --files-with-match `; do sed "s/\* including the terms and conditions of this license text as well. \*/* including the terms and conditions of this license text as well. */g" -i $file; done
Contrary to the doc comment, this function could never return false but
only cause a fatal error.

Importing the whole std namespace caused a problem with Clang and the
punning of bind and std::bind.

The Web's opinion of "using namespace std" also seems to be more against
than for.
