This RFE is actually a duplicate of

RFE => [ 1534420 ] new features for inkscape

I'm posting it because in that one horkana asked for a
detailed description of a problem, but i couldn't
upload the picture.

Therefore I'm adding a sketch of what's ment by TRIM
(sometimes called CUT, Virtual Segment Cut etc.) and
EXTEND.

I hope this is useful.
