[src/trunk]: src/usr.bin/make make(1): clean up code related to VarEvalFlags
details: https://anonhg.NetBSD.org/src/rev/97a7d66950ba

description:
make(1): clean up code related to VarEvalFlags
Mention VARE_WANTRES before VARE_UNDEFERR since the latter depends on
the former.
In ApplyModifier_Assign, VARE_KEEP_DOLLAR doesn't have to be removed
from eflags since ParseModifierPart does this already.
In EvalUndefined, testing for VARE_WANTRES is redundant if VARE_UNDEFERR
is already set.
