[PATCH/v3] bundle.c: added --stdin option to git-bundle

It seems that the consensus is that the other half of my original
patch is no good.  You have some pretty good ideas about how to
correctly address the problem I was trying to solve, and I look
forward to seeing them actually implemented.

For now, I offer separately the modification I made to bundle.c to
allow git-bundle to handle the --stdin option.  There is no
accompanying change to the documentation because it already implies
that this option is available.
