AFAIK, LaTeX allows to inline "\[...\]" constructs, so something like

  Some \[1+1\] text

is perfectly valid. Thus, I think we need to support them.

The other thing to consider is that having the same syntax for an inline
and a non-inline element could introduce some bugs (e.g. when filling
a paragraph).

OTOH, allowing inline \[...\] is pretty harmless.

This is a minor annoyance, indeed. However, you can use the verbose form
in this case (i.e., "\begin{displaymath}").
