I have thought about suggesting this myself, and your output for many of
the files matched my intuition, but some were grossly off, so I checked.
The above procedure counts commits, and a one liner "s/char \*/const &/"
weighs as heavily as the patch that implemented the whole thing, for a
file that was done in one commit almost perfectly except that it needed a
small constness fix. Summarizing output from "blame" for each file may
give you a more meaningful results:
# timestamp
ts='[12][0-9][0-9][0-9]-[0-9][0-9]-[0-3][0-9] ..:..:.. [-+]....'
# linenum
lno='[1-9][0-9]*'
git blame "$file" |
sed -e 's/^[^ ]* *(\([^)]*[^ ]\) *'"$ts *$lno"').*/\1/' |
sort |
uniq -c |
sort -r -n
For example, I do not think it is fair to credit me for abspath.c more
than Dmitry like this:

Initially Dmitry introduced this file with 5b8e6f8 (shrink git-shell by
avoiding redundant dependencies, 2008-06-28) at 68 lines. J6t added 36
lines for add_path() with 10c4c88 (Allow add_path() to add non-existent
directories to the path, 2008-07-21), I added 12 lines to add a new
function with 90b4a71 (is_directory(): a generic helper function,
2008-09-09) and then added a two-liner out-of-bounds-then-die check in
737e31a (make_absolute_path(): check bounds when seeing an overlong
symlink, 2008-12-17).
