The filter structure provides a mechanism for providing the working directory's file name path to a filter using a %f argument. This request is to teach the textconv mechanism to support the same capability. The use case comes from a complex content renderer that needs to know what the original file name is, so as to be able to find additional content, by name, that describes the file (base name+different extension). If this is considered a good idea, I would be happy to implement this but need a pointer or two of where to look in the code to make it happen.
