[Bug-readline] miscalculation with wrapped prompt line

[Per Bothner]

Consider a long bash prompt, with a dummy escape sequence:
PS1=ABCDEFGHIJKLMNOPGRSTUVWXYZ"[\#]"ABCDEFGHIJKLMNOPGRSTUVWXYZ:"\[\e[0m\]"

Now create a terminal emulator window (xterm works); make it narrow
(say 50 characters); type Enter (to get a fresh bash prompt).
Now type ctrl-R.  I see:

(reverse-i-search)`': RSTU

I.e. "RSTU" didn't get erased.

The TERM is xterm-256color.

I tried with bash from git, and same result.
