i noticed the following comment in lib/libc/shlib_version:
># - libc/gen/assert.c: __{diag,}assert13() -> __{diag,}assert()

	actually, i believe we can nuke all __RENAME(), covered by libc,
	when we increase shlib major (and then we will populate new __RENAME()
	whenever we make incompatible change without shlib major upgrade).
	am I correct?
