Porting patch(1) from NetBSD to FreeBSD (was Re: FreeBSD in Google Code-In 2012? You can help too!)

[hiren panchasara]

Thank you all for the inputs.
I understand this is a long grueling process so I will attempt to do things
in approximately following order:

1) prepare a new port for bsd patch
2) make sure new bsd patch has all options of existing gnu patch
3) merge outstanding patches:
http://svnweb.freebsd.org/base/head/gnu/usr.bin/patch/?view=log
4) bug compatibility
5) performance

cheers,
Hiren
