Processing @-commands within @displaymath could be useful for using
@macro's and consistency with @math.  Apart from that, the only
command that I can imagine people having to use inside @displaymath
would be @@ to get an @.

I don't think it matters that much.  Would you be able to implement it?
I made @displaymath a lot like @verbatim, but maybe there is another
command that is more appropriate.

People might also put other Texinfo commands inside the block, like
@sub or @sup, but that shouldn't be encouraged, as that won't work
with MathJax.  (Also, \mathopsup won't work with MathJax either.)
