I was testing what inspired me to write the original patch, and as I
seldom use anything of bash beyond bourne-shell / posix-shell features,
I never used $'\x{....} ever before, so now that we have it, I can make
it muscle-memory.

Thanks a *lot* for pursuing this! I'm going to use it all the time.
