Details:

i stumbled into this because i had the rdiff-backup testfiles.tar.gz open on
a partition which a cronjob backs up... top of CVS runs into some troubles
with long filenames.  here's one of the problems:

    mkdir test
    cd test
    mkdir `perl -e 'print "a" x 255`
    cd `perl -e 'print "a" x 255`
    touch `perl -e 'print "b" x 255`
    cd ../..
    rdiff-backup test dest
    cd test
    mv `perl -e 'print "a" x 255` `perl -e 'print "c" x 255`
    cd ..
    rdiff-backup test dest

basically the first rdiff-backup succeeds because it doesn't need to create
longer filenames from the long names... the second needs to create increment
files and it fails with the traceback
given below.

i think we should use magic random filenames in these situations and include
mapping information in the metadata file to resolve the problem... it's not
ideal, but it should do the job.
