ok, but it might even be more clever, like minimum number of glyphs on 
last line or so (and words in case of other scripts)

i had code for that but removes it as fonts are pretty inconsistent; i 
will look into that again when we have (1) a couple of reference fonts 
without bugs in the tex distribution and (2) wiki pages with info about 
the quality of fonts (can later become a database); otherwise we end up 
in messy support situations

that would be very helpful

sure
