Issue 2: Review of newline transformation rules:

Issue 3: Anyone know of further information on line-breaking rules
languages other than Japanese? We have a note collecting references
to further information that could use some help from i18n folks:

Issue 4: The 'letter-spacing' property as currently implemented puts
space between Arabic letters. Does this make sense? Should there be
some other behavior instead (e.g. suppressing letter-spacing)?
