git-apply: fix whitespace stripping
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.
