Yes, that should work as long as the file is modified and not added. You
can also say "4d77a3cee^:A/B/C" if you do not want to look up the parent
Note that for a merge commit with multiple parents, the question is more
complex, as there are two previous states that are merged.
You say that it doesn't work in one particular case. What is that case?

Running "git fsck" can tell you if there is repository corruption.

Probably. Can you show us the commit that fails? What does git say when
you try it?
