It makes it more consistent with the patterns in the md file.
Moreover, if you introduce a shortcut, it is not obvious what is being
abbreviated. Does "&r" stand for "+&r" or "=&r" ?
You know now that you want it to mean "+&r", because that is what you want
to express in the first place, but when some month later someone reads
such code, this context is not there.
