options `start' and `stop' now (unless I have forgotten any). This allows

The (42 or so) ports that already DTRT before are unchanged.
Now try to use those variables everywhere around DIST* and PATCH*
definitions as far as possible, for ease of the future updates and the
neatness.
Okay, 60% of `japanese' ports have been done. :)
