The algorithm isn't right here: it accumulates any set of 8 spaces into tabs even if they're separated by tabs, so <four spaces><tab><four spaces><tab> is converted to <tab><tab><tab> when it should be just <tab><tab> So teach git-apply that a tab hides any group of less than 8 previous spaces in a row.
