Me too. Although I opted for a function in avrftdi (again, not yet committed).

b).
Also, I would propose that the macro prints the programmer name (if the message
is generated by a programmer) or "avrdude: " if it is generated by "general"
code.
What do you think about printing the function name and line number by directly
by the macro, if the verbosity level is high enough (3 or so)?
