Thanks for the cleanup.

You may have overlooked the fix for udev_config.c(parsing udev.conf) in
your patch.  So, I've adapted the fixes you applied to namedev_parse.c
to this file also.

Also, while 'eating' the whitespace the 'count' doesn't get decremented.
This leads strncpy to copy the number of whitespace minus 1 characters
from the next line. Minus 1 because it copies '\n' from the current
line.

		while (isspace(bufline[0])) {
			bufline++;
+			count--;
		}
		.
		.
		.
		strncpy(line, bufline, count);

Included patch(against udev-030) contains the above fixes as well as
your fixes.
