[AUCTeX] TeX-insert-macro no braces in math mode

[Uwe Siart]

Hello,

TeX-insert-macro in math mode does not behave like I would expect. But I
can't tell if it is a bug or not:

In text mode when I mark a letter (say "A") as region and type "C-c RET
macro" I get \macro{A} with braces around A.

The same in math mode gives me \macroA (no braces).

Is this intended? It does not make much sense to me since \macroA
certainly won't work.
