Second thoughts after agreeing to change something are okay.  Keeping
them for yourself not so much, because it deprives your reviewers of a
chance to raise further points.

In this case, the point I didn't make because I wanted to reach
agreement on contents before nitpicking form: you're not using
warn_report() the way it wants to be used:

    /*
     * Print a warning message to current monitor if we have one, else to stderr.
     * Format arguments like sprintf(). The resulting message should be a
---> * single phrase, with no newline or trailing punctuation.
     * Prepend the current location and append a newline.
     */
    void warn_report(const char *fmt, ...)

Please tidy up.
