Based on these comments and the remarks by Alvaro and Andres, I think
it's clear that we should reject this patch.  The number of patches
that get through with -1 votes from 3 committers is very small, if not
zero.  While I like the feature in the abstract, I agree with Tom that
it would be better to wait until we have more clarity about what the
semantics are supposed to be.

I will update the CommitFest app accordingly.
