| Linus was friendly enough to give us permission to use tabs. He forces tabs 
| for indentation, but leaves it up to everyone else to (1) set their editor 
| to show tabs as 2 or 4 or whatever, and (2) use spaces for alignment.
|

| some degree of freedom for some people to vary this *AND* have decent 
| looking alignment for *EVERYONE* by allowing them to use spaces for 
| alignment.
| 
| Nothing in the codingstyle document confirms or denies this, so I will 
| assume that it is _allowed_ to use spaces for alignment.

Actually that is exactly what I was expecting to see. Thanks a lot.

| 
| the checkpatch.pl script doesn't disallow spaces for alignment - it is dumb

| 
| That is and was the whole point... and worth the addition to CodingStyle
