Feature or enhancement

Proposal:

Currently the indent is generated from scratch for each depth:

_current_indent_level += 1
newline_indent = '\n' + _indent * _current_indent_level

We can easily re-use the old indent:

newline_indent = old_newline_indent + _indent

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
