comparison genshi/output.py @ 658:a445c9e5ee96
The `TextSerializer` class no longer strips all markup in text by default, so that it is still possible to use the Genshi `escape` function even with text templates. The old behavior is available via the `strip_markup` option of the serializer. Closes #146.
