[web2py] Problem with response.files.append

[Miguel Lopes]

I have an app running smoothly on OSX that fails on Windows XP.
I've traced the cause to the use of response.files.append(URL(...)) in views
that extend layout

In OSX this works with web2py 1.74.4:

{{response.files.append(URL(r=request, c='static/biz', f='common.js'))}}
{{response.files.append(URL(r=request, c='static', f='dashboard.css'))}}
{{response.files.append(URL(r=request, c='static/jquery-autocomplete',
f='jquery.autocomplete.css'))}}
{{response.files.append(URL(r=request, c='static/jquery-autocomplete',
f='jquery.autocomplete.js'))}}

{{extend 'layout.html'}}

In Windows XP with both web2py 1.77 and 1.78.2 doesn't work!
