Then we write a formal guideline. It really isn't fair to new developers
to not have any idea how they are going to be able to get a patch
applied to older branches. Something like:

Generally speaking we adhere to the following guideline for patches.
* Security fixes are applied to all applicable branches.
* Bugfixes are applied to all applicable branches
* Note: A patch that addresses a known limitation is generally
not backpatched
* New features are always applied to -HEAD only.

This is not a policy as much as a legend for developers to consider
before they submit their patch.

If we do this, we have the opportunity to just point to the FAQ when
there is no ambiguity. It also increases transparency of the process;
which is always a good thing.
