Didn't manage to find RTE settings to avoid losing leading whitespace of
lines, so reindeint arch after doing all integration, right before saving back
to view's field.
* html.fromstring(parser=HTMLParser(remove_blank_text=True) does not seem to
work, so serialize to XML, and parse back with
remove_blank_text. remove_blank_text necessary for lxml's pretty_print to
work correctly.
* pretty_print only & always uses 2 spaces/indent level. Our files (and the
HTML editor's Format button) uses 4 spaces -> need a second pass to double
indents.
