[web2py] Recent change to string escaping breaks dynamic javascript

[Michael Ellis]

I've got an app with views that generate jQuery code on the fly.  This was
all working fine until recently, i.e. sometime after 1.92.  With more recent
builds, single and double quotes in strings are now escaped and it breaks
the javascript.   Here's an example

The view has (with much snipped out):

{{
schartoptions = """{
    type: 'bar',
    barColor: 'green',
    chartRangeMin: '%d',
    chartRangeMax: '%d'
    }
    """%(chartmin,chartmax)
}}

and later on I use the variables within a script tag, e.g.

<script type="text/javascript">
    /* <![CDATA[ */
    $("#{{=ks+kc}}").sparkline(data.wsc.{{=ks}}.{{=kc}}, {{=schartoptions}}
</script>

With an earlier web2py, it produces the desired result,

$("#solution0").sparkline(data.s.solution0, {
    type: 'bar',
    barColor: 'green',
    chartRangeMin: '0',
    chartRangeMax: '1'
    }
    );

but now (at tip) I get

$("#solution0").sparkline(data.s.solution0, {
    type: &#x27;bar&#x27;,
    barColor: &#x27;green&#x27;,
    chartRangeMin: &#x27;0&#x27;,
    chartRangeMax: &#x27;1&#x27;
    }
);

Was this change intentional?  If so, what's the recommended workaround?

Thanks,
Mike
