Author: Free Ekanayaka <free@64studio.com>
Reference: man dhclient.conf
The only difference with the reference syntax is that this lens assumes
that statements end with a new line, while the reference syntax allows
new statements to be started right after the trailing ";" of the
previous statement. This should not be a problem in real-life
configuration files as statements get usually splitted across several
lines, rather than merged in a single one.
TODO: support the "default", "supersede", "append" and "prepend"
