This is exactly what I was looking for! Thank you!

I understand that in some cases this can give me two paths instead of
one, but it will only demonstrate that I have absolute copy of a file
inside my repo, which is also good to diagnose (because the
probability of having two meaningful files with the same hash, but
different content is way too low).

So, this means that after few little tricks the keyword expansion
problem may be resolved by only using $Id$ keyword.
Because after having this hash one can build up all necessary info from it:

#finding blobs with SHA indicated in $Id$ keword
$ git log --no-abbrev --raw --all | grep SHA-1

# little script or regexp here (don’t have it)
$ pull out path from result

# last commit for the path with all corresponding info
$ git log -1 HEAD path

So, this seems to cover most of the needs of people who would like to
use keywords expansion, if they are not ready to forget about them…

Does it make sense?

Thanks,
Eugene
