Makeing fetchindex really mirror INDEX

[Simon L. Nielsen]

Hello

I patched fetchindex to really only download a new INDEX if it's
changed and to only uncompress INDEX.bz2 it's newer than INDEX.  Patch
should be attached.

Any complaints to committing this?

BTW. the mirror mode fetch(1) is broken in at least FreeBSD 5.3 and
newer, but seems to works on 4.10.  I have made a patch [1], which I
hope to get committed soon, so if the fetchindex patch don't work for
you that might be the reason.
