The command "git rebase --whitespace=fix HEAD~<N>" is supposed to only clean up trailing whitespace, and the expectation is that it cannot fail. Unfortunately, if one commit adds a blank line at the end of a file and a subsequent commit adds more non-blank lines after the blank line, "git apply" (used indirectly by "git rebase") will fail to apply the patch of the second commit.
