*blush*

It happens like this... imagine you are using someone else's computer, you 
have a simple one line patch to fix, and can't be bothered downloading 69 
MB of source... (let alone git clone)

$ vi p
$ curl 'http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plain;f=drivers/net/lib8390.c;h=789b6cb744b284ee08d4c749ab9fa210dc34170e' >m
$ patch <p
can't find file to patch at input line 8
Perhaps you should have used the -p or --strip option?

Thanks. I'd hate to screw it up a 4th time!

I'll avoid shortcuts next time.
