Merge branch 'jc/doc-rebase-fuzz-vs-offset-fix'

"git rebase --help" referred to "offset" (the difference between
the location a change was taken from and the change gets replaced)
incorrectly and called it "fuzz", which has been corrected.

* jc/doc-rebase-fuzz-vs-offset-fix:
  doc: difference in location to apply is "offset", not "fuzz"
