Hi David,

Correct me if I am wrong, but the second definition is usable as a 
function.  That is, it cannot accept a parameter for customizing the 
markup.  Unless `\etc` is something magical that is undocumented, the 
resulting `\doubleBox` would have to be a complete idea.

It would seem Urs' version is necessary if you need to be able to 
provide a parameter, which more closely matches the intention of the 
original `\doubleBox` as a markup function.
