Recent patch in handling of \' broke latex terms

[Ethan A M. <merritt@u.washington.edu>]

I am now getting error build errors from the latex tutorial
subdirectory:

Making all in tutorial
make[2]: Entering directory `/home/merritt/cvs/gnuplot-cvs/tutorial'

set xtics ('$-\pi$' -pi, '$-\frac{\pi}{2}$' -pi/2, "0" 0, '$\frac{\pi}{2}$' 
pi/2, '$\pi$' pi)
                                               ^
"eg5.plt", line 14: invalid expression

make[2]: *** [eg5.tex] Error 1



I suspect the culprit is this patch:

2005-11-24  Juergen Wieferink  <wie...@fr...>
        * src/util.c (parse_sq) src/scanner.c (scanner) docs/gnuplot.doc:
        Fixed \' in single-quoted strings.

I'm not entirely certain, however.  In any event it broke very recently.
