I don't find that reason particularly compelling -- people could want
to search for any error message, or they could equally want to be able
to read it without Google translate. Guessing which messages are
obscure enough that we need not translate them exceeds my powers. If I
were doing it, I'd make it errmsg() rather than errmsg_internal() and
let the translations team change it if they don't think it's worth
bothering with, because if you make it errmsg_internal() then they
won't see it until somebody complains about it not getting translated.
However, I suspect different committers would pursue different
strategies here.
