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.

Before, would save view section itself (including root element). But
branding distribution (and thus editability) are set on the last
programmatic root, thus the root element may well be generated
e.g. <span t-att-foo> will define the span itself as editable.
Saving this would remove the programmatic content on the node, and
thus break the view section altogether.
Fix the issue by only saving the root's content in the previous root.
