Thanks, but these questions are simple sanity checks done by contrasting
your design with _existing practices_, if any.  It is not useful to answer
what you did here, only to contrast your design with itself.

Also we can read them from your implementation ;-).

Now how did you get the compiler error messages from your example from the
files in HEAD commit without checking them out?

Besides, that question is still part of figuring out prior art done in the
git-unaware grep, so it is irrelevant that sed or other people's grep
cannot peek into HEAD.
