How about proceeding like this: merge as-is and trust the callers to
know what they're doing, so that I can spend some time on implementing
these flags? It'll be tedious work, but it shouldn't require too much
brainpower. The alternative (blocking StringNG until the conversions
work is done) would stall StringNg even more :(
