To me, it seems what you want to do is convert the commit ID in front of
every blame-line into the result of running 'git name-rev' (or 'git
describe') on that line.
To that effect something like this should work:
git blame <file> |
while read sha1 rest
do
tag=$(git name-rev --tags --name-only $sha1) &&
echo "$tag $rest"
done
Of course, if you're doing this at a bigger scale, you want to wrap this in
a script that (1) caches commitID -> tag mappings, and that (2) runs 'git
name-rev in its --stdin mode'.
Have fun! :)
