Currently \def is used for all math macros that have no option

(if you really do want to override the command, you can just put
\let\mycommand=\undefined in your LaTeX preamble, although with
unicode-math I often have to put this in an \AtBeginDocument).
This very simple patch just makes LyX always output \newcommandx
instead of \def for math macros.
Unfortunately, this means if you want to have any math macros
you'll always need the xargs package (but it's a small package
release all they way back in 2008 and is included in TeXlive),
hopefully this won't annoy users too much.
Since we already depend upon xargs, this won't be a problem.
However, I think this might count as a format change, because it
changes the exported LaTeX. If so, then it would have to wait for
2.5.0. But I'm not sure about this, and perhaps the people who
actually know about this will think it's safe. I'd like to hear.
Independently from that, this is a change that needs a lot of testing
and it is risky to perform near a release.
Yes, I decided not to mention that, since the format change decides it
anyway.
It's unfortunate, but perhaps we can get 2.5.0 out sooner...
