OK, that might be somewhat unsatisfying from end-user's point of
view (logically "test-blob-1" is already a name based on the 'graph
relations' that is satisfactory).

	[side note] should that grep become test_i18ngrep?

If this machinery is to find an object that is *bad* (in the sense
in one of your earlier messages), I suspect it may be quite easy to
use the new mechanism added by the series to also locate a tree
object and report "that tree appears in this commit at this path"
and it would be equally useful as the feature to find a blob.

Thanks.
