git-blame --incremental
This adds --incremental option to help GUI porcelains to show the result from git-blame incrementally. The output gives the origin information in the same format as the porcelain format. The first line has commit object name, the line number of the first line in the group in the original file, the line number of that file in the final image, and number of lines in the group. Then subsequent lines show the metainformation for the commit when the commit is shown for the first time, except the filename information is always shown (we cannot even make it conditional to -C option as blame always follows the renaming of the file wholesale).
