Yes, I also considered changing "from" to "show peer" which might have
been nicer. I am not opposed to such a cleanup, but again, not sure if
it worth it now that we are merged.

I agree, though I don't feel qualified to comment on what other places
that should be used (I was a bit surprised to find out that
find_unique_abbrev ever returned NULL, but changing the semantics at
this point is probably going to cause some subtle bug).

Oops, yes. I think it should be hard to trigger (both commits would have
to either not be in your db, or not be unique to 40 digits). But clearly
it should be fixed, and it looks like Junio did.

It was a stupid cut-and-paste from Nicolas' fetch code, but it looks
like he correctly allocates 84 bytes for the "..." case.

Sorry, I don't see the style nit you're mentioning here.
