Having played with that problem a bit, I'm almost certain that was the
problem.

Not only that, but you can use control characters as delimiters; I think
"mm" (and maybe some other macro packages) use ^G (control-G, ASCII BEL,
'\007') as a delimiter.  Why they chose \(ts, I dunno, unless they were
afraid that some macro package had usurped ^G, in which chase whey they
didn't choose ^A or some other control character, I dunno....
