Here we change the magic callout part number selector to the new
atribute syntax. The syntax to select the second part of the callout string:
'%2c' is now '%c{2}'
I think it's more clear and we no longer misuse the length argument.
The old syntax is still supported, but we should remove it some
time in the future.
