An error message is already printed by sha1_object_info itself, and the failed entries are additionally marked in the listing.

> printf ...Tried. Makes exactly this code much uglier, and the pathname is printed nicely quoted after the outer if() is closed. And I don't like the idea of dying here: it'll take longer to collect all the needed entry names for later recovery (that's how it came to the change, AFAIR).
How about this patch instead? I chose "BAD" for the marker, as any automatic processing trying blindly to convert it into a number will get a 0, which seems safe to me.
