Change subject: Fix whitespace preservation around meta items
......................................................................
Fix whitespace preservation around meta items
This was broken, especially in wrappers.
Changed the wrapping algorithm so that meta items are placed outside
wrappers if possible. On the left-hand side, this is already the case:
we don't open wrappers for meta items. On the right-hand side, this is
accomplished by buffering the meta items and only inserting them when
we encounter either real text (not whitespace) or the end of the wrapper.
If we're interrupted by real text, we insert the meta items with the
unmodified whitespace. If we're interrupted by the end of the wrapper,
we insert the meta items outside of the wrapper with whitespace stripped.
Internally, this is done by stripping the whitespace into the whitespace[0]
of the meta item to its right. Then when we output the meta items, we
either decide to 'restore' the whitespace, or to 'fixup' by also setting
whitespace[3] on the element before the whitespace.
