using Paste's proxy-prefix with inherited ini files?

[Jonathan Vanasco]

I'm cleaning up a deployment and ran into something that I don't quite understand.

If I apply a `filter-with` in a base.ini file, I can't overwrite (or append) any values in a derivied.ini

for example:

base.ini

[app:main]

use = egg:MyApp

foo = bar

filter-with = proxy-prefix

[filter:proxy-prefix]

use = egg:PasteDeploy#prefix

derived.ini

[app:main]

use = config:base.ini#main

foo = biz
                bar = foo

Running `bin/pserve derivied.ini` will not put the foo/bar values into the settings.

the `set foo=biz` syntax won't work; and I couldn't get the pipeline command to affect this either

the values show up in global_config, set to my_app.main(global_config, settings)

does anyone know if it's possible to set up the filtering in a base ini and still inherit?

I just migrated the filter into derived.py and everything works as expected.  I'd rather de-duplicate this if possible though.
