Doc about Swapfile is old.

[Ronald Klop]

Hello documentation team,

FYI.

Today I tried creating a swapfile on FreeBSD 10-CURRENT using this  
documentation.
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/adding-swap-space.html

It did not work and some googling gave me this commit which describes the  
right way to configure this.
http://lists.freebsd.org/pipermail/svn-src-head/2013-June/048862.html

I don't know if the handbook is only for stable/release.

Regards,
Ronald.
