This part needs to be qualified. "Natural" is of course in the eyes
of beholder. If we assume that your #1 holds true (i.e. the tuple
<in which tree object are we reporting, what path we saw hits> is
important and merging them into one <in what blob we saw hits> lose
information), then it is natural to ask "inside origin/master tree,
where do I have hits? By the way, I am only interested in builtin/"
and get "origin/master:builtin/pack-objects.c" as an answer (this is
from your earlier example), than asking "inside origin/master:builtin
tree, where do I have hits?"
If we do not consider #1 is false and the tree information can be
discarded, then it does not matter if we converted the colon after
origin/master to slash when we answer the latter question, and the
latter question stops being unnatural.

And if we want to keep the <tree, path> tuple, but still want to
make it easier to work with the output, allowing A:B:C to be parsed
as an extended SHA-1 expression would be a reasonable solution, not
a work-around. The answer is given to the question asked in either
way (either "in origin/master, but limited to these pathspecs" or
"in the tree origin/master:builtin/") without losing information,
but the issue you had is that the answer to the latter form of
question is not understood by the object name parser, which I
personally think is a bug.
