Unfortunately it also wouldn't always work, because ^H only moves the 
cursor, so if the next thing is a newline, the '@' wouldn't actually get 
deleted.

I suppose "%@am" could mean prepending an '@' when a domain is present, 
similar to how "% am" would mean prepending a space and "%+am" would 
mean prepending a newline. With that, "%al%@am" would be equivalent to 
"%ae".

But that then raises the question whether it should be implemented just 
for "%@[ac][mM]", or for all placeholders. In any case, I don't think it 
needs to be part of the changes at hand.
