What I mean is that the callers should tag their messages with the
type of the message, and let the logging framework decide whether to
print it or not.
There are some tiny performance optimizations, like
- if (be_verbose_global)
+ if (loglevel & LOG_DEBUG)
string spaces = "";
for (size_t i = 0; i < state_stack_.size (); i++)
spaces += " ";
- progress_indication (string ("\n") + spaces + string ("[") +
+ debug_output (spaces + string ("[") + file->name_string ());
you could just drop the if in this case.

Also, in lilypond, the difference between (non_fatal) error and
warning never has been very clear. Maybe we should just have a
fatal("..") // exits
error("..") // does not exit, but sets return status = 1
warning("..") // prints, succesful exist status.
