[gentoo-pms] [PATCH] How about a \ChangeWhenAddingAnEAPI marker?

[Ciaran McCreesh]

It's easy to miss some places that have to be updated when adding a new
EAPI. This hack fixes that. It works like this:

In pms.tex, at the top, we say

    \CurrentEAPIIs{4}

Then everywhere where we have EAPI dependent content, we put

    \ChangeWhenAddingAnEAPI{4}

which we can then grep for. Also, if you change the current EAPI, and
forget to change any of the markers, an error is produced.

I've not updated everywhere that needs this yet; there's just one
example. There might be a better way of getting the same effect. If not,
I'll go through carefully and put these in before we start work on 5.
