Well, it's a matter of preference. I prefer -u diffs, I usually find
them easier to read than -c diffs. :)

Something like this was brought up by Torsten to me before, I think it
will be great if we can somehow let the checksum ignore the difference
is compression formats. Since some master sites already do
recompression, this will free us from some of the "checksum mismatch"
errors (note that they can have the same filename (with .gz suffix)
and still have different checksums).
Also, we should be able to save space on wcarchive (and mirror sites)
by doing znew --best on all the distfiles.
The only problem is, how? I couldn't come up with a way to implement
this without having to gzcat the file every time a user types "make
<something>" ('cause most of the targets depend on "checksum"), or
forcing a znew from bsd.port.mk.
