well I added an accelerated version and that runs in 25% of the time needed by the repr
approach

the timings are roughly
Time for 10000x4 uses of <function _escape20 at 007FB9E4> = 1.84" Andy's < Python 2.1
Time for 10000x4 uses of <function _escape21 at 007EA91C> = 8.47" Robin's effort
Time for 10000x4 uses of <function quote_ps_string at 0080CF84> = 3.75" Bernhard's
Time for 10000x4 uses of <function _escapeLambda0 at 0080CFB4> = 2.97" Michael's
Time for 10000x4 uses of <built-in function _instanceEscapePDF> = 0.40" Robin's C extension

so I will code
        if extension: extension
        elif version<2.1: Andy
        else: Mike
