As someone else already pointed out, there are good reasons to do so, when you
want to treat a macro, as more as possible, like a function.
Another general C-style guide, with examples about it, is the following:

unfortunately there are no links to paragraph, so you will have to look for the
title "Macros" (about in the middle of the document)
