maybe we need a command:

Given this SHA1, tell me anything you know about it,
Is it a {blob,tree,commit,tag}?
Is it referenced from anywhere else in this repository and if so, which type?
And if it is not referenced, nor an object, tell me so explicitely.


This would have helped a lot for this confusion:

    $ git frotz 280c12...
     No object exists with such a substring (either as prefix, postfix
or in between)
     No other object is referencing any object containing this
substring as pre/post-fix

and this issue would have been resolved in a heartbeat.

Specially the verbose feature is contradicting the terse unix style though
and this command is tailored to this issue, so I don't know if it's any useful
outside this specific problem.
