fade=in:10:20,fade=out:50:60
could be supported as:
fade=in:10:20:50:60

and
fade=out:10:20:50:60
to black a part out (currently not supported with individual filters easily)

and more than 2, that is N such fade in/outs in a single filter would also be
usefull
for example consider that someone concatenates videos from several scenes to
make a movie. She might want to create fade out+fade in at the transitions
