git_blame_buffer

Version:

Get blame data for a file that has been modified in memory. The blame parameter is a pre-calculated blame for the in-odb history of the file. This means that once a file blame is completed (which can be expensive), updating the buffer blame is very fast.

Lines that differ between the buffer and the committed version are marked as having a zero OID for their final_commit_id.
