OK, some commands could move to BRACE_arguments if we want to ignore spaces
in their arguments.

@math isn't currently in BRACE_arguments and as spaces don't need to be
ignored for @math (I haven't checked whether they are or not), it's fine
to leave it out.

I see you have made some changes to the command types.  @value and @verb are
now BRACE_other (along with @w).  I guess @value is special because it
is expanded immediately, and @verb and @w also are handled uniquely.

I looked through command_data.txt and your list of commands
where spaces around arguments can be kept - @dmn, @key, @indicateurl,
@titlefont - appears sensible to me.  I don't know how easy it would be
to change any of these.  Would you be moving them to BRACE_style_other?
