PS1 will not be updated until the next time the shell either prints the
prompt itself or calls readline().

The command you execute after doing the history edit effectively happens
during the same call to readline().  readline() doesn't return until you
accept the line with a newline, and the shell doesn't update PS1 until
after readline() returns, the command is executed, and it's ready to call
readline() again.
