Shawn O. Pearce 741659fed4 DeltaStream: Fix data corruption when reading large copies If the copy instruction was larger than the input buffer given to us, we copied the wrong part of the base stream during the next read(). This occurred on really big binary files where a copy instruction of 64k wasn't unreasonable, but the caller's buffer was only 8192 bytes long. We copied the first 8192 bytes correctly, but then reseeked the base stream back to the start of the copy region on the second read of 8192 bytes.

Shawn O. Pearce 741659fed4 DeltaStream: Fix data corruption when reading large copies

If the copy instruction was larger than the input buffer given to us,
we copied the wrong part of the base stream during the next read().

This occurred on really big binary files where a copy instruction
of 64k wasn't unreasonable, but the caller's buffer was only 8192
bytes long.  We copied the first 8192 bytes correctly, but then
reseeked the base stream back to the start of the copy region on
the second read of 8192 bytes.  Instead of a sequence like ABCD
being read into the caller, we read AAAA.
