fileset: treat encoding and eol as the predicate calling _existing Before this patch, predicate function 'encoding' and 'eol' aren't listed up in '_existingcallers', even though they invoke 'existing()'. This causes unexpected failure of these predicate, if there is a (manually) deleted file in the working directory. 8a0513bf030a and 3ce3f2b059a1 seem to overlook putting already existing 'encoding' or newly introduced 'eol' into '_existingcallers'. This patch also changes order of fileset "eol(unix)" output in test, because "existing caller" predicates show "A(dded)" files before "C(lean)" ones.
