* Code for assignment, conversions now mirrors spec. * Changed some snprint -> smprint. * Renamed runtime functions to separate interface conversions from type assertions: convT2I, assertI2T, etc. * Correct checking of \U sequences. Fixes #840. Fixes #830. Fixes #778. R=ken2 CC=golang-dev https://golang.org/cl/1303042
