Fixed consecutive lines with same blame info not appearing in blame.

This fixes a bug when parsing blame -p output: Full commit info headers
only appear for the first line from a particular commit, but other lines
were ignored as the blame info dict was reset after each line.

This patch handles both multiple consecutive lines from a commit and
interleaved lines from multiple commits.
