I realized that there was only one other local label in s_lock.h,
so that
+ * Ordinarily, we'd code the branches here using GNU-style local symbols,
felt a little silly: local labels would now be the minority usage.
And to me, this approach is actually superior to a local label.
"1:" has zero mnemonic value while "TAS%=_fail" conveys something
useful. So I converted that other usage too and documented this as
the new standard approach for s_lock.h. Pushed at 0c9f46c42.
