Did not remove calls to stdnse.silent_require since these can be used to
abort script execution if OpenSSL is not included, even if the script
does not directly call openssl.* (perhaps it uses comm.tryssl instead,
for instance).
Also did not remove require "strict", since that library is special and
modifies the environment.
Mostly in documentation (the description field, for instance), but also
some long literal strings. Lua 5.2 introduces a string escape, "\z",
which escapes any amount of subsequent whitespace, including newlines.
This can be used to wrap string literals without upsetting indentation.

Mostly found with:
for i in nselib/*.lua scripts/*.nse; do
echo $(perl -lne 'BEGIN{$a=$p=0}next unless $_;/^(\s*)/;' \
-e '$l=length$1;next if$l==$p;$a+=(abs($l-$p)-$a)/$.;' \
-e '$p=$l;END{print$a}' $i) $i
done | sort -nr
And indented with: https://gist.github.com/bonsaiviking/8845871
whois-ip.nse was particularly mangled (probably my fault due to using
vim's built-in indentation script, but it could be structured better)
