When "git push" triggered the automatic gc on the receiving end, a
message from "git prune" that said it was removing cruft leaked to
the standard output, breaking the communication protocol.

The output from "git diff -B" for a file that ends with an

In the next major release, we will switch "git push [$there]" that
does not say what to push from the traditional "matching" to the
updated "simple" semantics, that pushes the current branch to the
branch with the same name only when the current branch is set to
integrate with that remote branch (all other cases will error out).
