Sorry, it turns out I've misremembered: string-width doesn't account
for "automatic compositions", the ones that happen due to
composition-function-table (as opposed to "static compositions" which
happen due to the 'composition' text property).  So this case
currently cannot be handled correctly by string-width; we should fix
that.
