Turning off math escape mode in chpl2pdf
Turning off math escape mode in chpl2pdf

In the listings package, math escape mode permits LaTeX math mode
to be entered via $ within a code listing.  We use this within
the spec to insert nicely formatted "..." and subscripts within
code segments.  Its use also forces us to insert an ugly mbox in
order to refer to sync variables using $ like "flag$".  John
Lewis found that this was a problem for using chpl2pdf on code
that uses sync variables.

This fix turns off math escape mode for the chpl2pdf script.
Arguably, we could/should also support such an environment
for use within the spec in code that is sync variable heavy
but doesn't use many other features for math mode.
