Re: @macro to accept hyphen

[Christopher Dimech]

Have not seen a mathematical expression in the manual. Thusly I have provided
you with one.  Works perfectly, no problem with it. 

You have this sentence in the macro. 

To get a single ‘\’ in the macro expansion, use ‘\\’

Although the information is there, it is very cryptic.  If we include an 
indented
example with a real math expression, users will be immediately drawn to it.
