Erik Demaine 1512de5b35 Reset to leftmost spacing mode after newline (#1841)
* Reset to leftmost spacing mode after newline

Newlines have class "mspace newline" but shouldn't be fully ignored:
they should reset the spacing mode back to "leftmost" so as to not
accidentally create trailing spaces at end of lines.  Fix #1828.

* Update snapshots

* Add root detection, and treat newline specially only then
