Pull up following revision(s) (requested by tron in ticket #772):
lib/librefuse/refuse.c: revision 1.96
FUSE seems to allow short writes without errors but PUFFS doesn't. Work
around this by returning ENOSPC in case of a short write to avoid protocol
errors. This change is based on problem analysis provided by Antti Kantee.
This fixes PR lib/45129 by myself.
