I have reservations about making it a macro, because that would
confuse debuggers and any profilers that do basic-block or line-level

I also don't mind cluttering the function.  The value of
a low-level I/O API like apr_brigade_puts() is that it hides
ugly bufer management details from application code, so that
the application code can stay clean and simple.
