If you need a generally indentable/outdentable stream, you might try
the class documented here:
The code is at:
IndentedStream is intended for generating Python or XML output, so it
manages a stack of indent levels which can be pushed and popped. It
also does its indentation lazily, so that if you output a newline and
then change the indent level, it won't have indented the new line yet
unless something was written to the new line.
