Oh wait, I see my mistake.  The comma form is the same as multiple
"mach" form.  So in the second pattern, the [!0-9] matches the dot
between "5.1" and the trailing asterisk gets the trailing "1".

I think using the [!0-9] is a little non-intuitive, I like the
2.[0-9].* form better, I can use a comma instead of two "mach" lines
if you prefer.

So okay with the aforementioned pattern change?
