I would do it differently. If we know the thing is a simple string, we
can stick it in bug_entry and print from __report_bug() without causing
horrific shite at the call site.

The problem with WARN() is that it is a format string, which must be
filled out in situ. Resulting in calls to snprintf() and arguments and
whatnot.
