"My #1" is really "what I inferred from your statements." I did not think the tuple was important, but I agree that may be my shortsightedness. If the tuple is important, then it seems to me that the --null behavior is a bug (the colon is left intact); but changing it now seems senseless or harmful. > then it is natural to ask "inside origin/master tree, > where do I have hits?

I am beginning to agree, though we discovered some other weird output from grep which also does not parse. (origin/master:../relative/path). It seems that fixing this bug could be very confusing for get_sha1_with_context unless the context was rewritten to match the traditional syntax.
