[Slackdocs] Slackbook / Minor typo

[Xavier Belanger / Ellendhel]

Hi,

Not really a typo, but there is a paragraph that doesn't really
make sense on the same page:

 [ http://docs.slackware.com/slackbook:linux_kernel ]

> Here you can see that I the new kernel I am compiling has added
> support for a new filesystem: ext4.

"I the new kernel"; personally I have never seen a kernel able
to decide to compile itself :-)

> Typically it is save to choose the default option

I'm assuming "it is safe" here.

If anyone can edit and fix this, that would be nice.

Thanks!
