The fix is being released in 1.9.9.

The same changes are also being back-ported to 1.10.1 for consistency, although the bug did not affect 1.10.x.

> There is an error in the checksum code added to 1.9.7 to detect SHA1 collisions. The expanded length is calculated incorrectly and when the delta length is a multiple of 16K the checksum calculation stops early and fails.
> Symptom: Commits fail with a false "Filesystem is corrupt" error.
