Sounds like a reasonable request.  Also I am seeing:

    diff.c: In function 'scan_word_boundaries':
    diff.c:512: warning: enumeration value 'DIFF_WORD_UNDEF' not handled in switch

from this part of the code:

	for (i = 0; i < len; i++) {
		switch (buf->boundaries[i]) {
		case DIFF_WORD_BODY:
			*p++ = text[i];
			break;
		case DIFF_WORD_END:
			*p++ = text[i];
			*p++ = '\n'; /* insert an artificial newline */
			break;
		case DIFF_WORD_SPACE:
			*p++ = '\n';
			break;
		case DIFF_WORD_SKIP:
			/* nothing */
			break;
		}
	}
