Gary V. Vaughan d43b40113e syntax-check: [REDO] fix violations and implement sc_prohibit_test_const_follows_var.
To safely use a non-literal fist argument to 'test', you must
always prepend a literal non-'-' character, but often the second
operand is a constant that doesn't begin with a '-' already, so
always use 'test a = "$b"' instead of the noisy 'test "X$b" = Xa'.
* cf.mk (sc_prohibit_test_const_follws_var): New syntax-check
rule to ensure we don't reintroduce noisy test operands.
