Log message:
Remove all the "assert(len>0)" which forbade zero-length writes across the
from_backend() interface, after having made all implementations safe against
being called with len==0 and possibly-NULL/undefined "data".
(This includes making misc.c:bufchain_add() more robust in this area.)
Assertion was originally added 2002-03-01; e.g., see plink.c:1.53.
I believe this now shouldn't break anything.
This should hopefully make `ppk-empty-comment' finally GO AWAY. (Tested
with Unix PuTTY.)
