[XeTeX] Overfull \hbox when using inline math scripts

[Conrad Scott]

Dan,

One possible solution for the particular example you posted (see below) 
is to allow line breaks at commas in inline maths. The solution I use 
for this is:

\mathchardef\breakingcomma\mathcode`\,

{\catcode`,=\active

\gdef,{\breakingcomma\discretionary{}{}{}}

}


\newcommand{\mathlist}[1]{$\mathcode`\,=\string"8000 #1$}


which I took from the answer by egreg to the following stackexchange 
question:

http://tex.stackexchange.com/questions/19094/allowing-line-break-at-in-inline-math-mode-breaks-citations


You could use this as "Let the tuple $(\mathlist{X, Y, Z, A, B, C, +, x, 
-, !, \#})$" in your example.


There are some other solutions in that post and the other it links to.


All my best,
Conrad
