[Bug-readline] c + movement in vi mode

[Aryeh Leib Taurog]

Hi,

I don't know if this is a bug or not, but I am not sure where else to 
ask.  I am very grateful to have gnureadline, maybe I just some 
guidance configuring it.

When using bash in vi mode, I can combine the 'c' command with a 
multi-keystroke motion just like I do in vi.  i.e. I type

psql -t -A -f myscript.sql<ESC>0ctm

I am now changing the command line up to the filename myscript.sql

When I try this elsewhere, it doesn't work.  For example in python 
when I type "datetime.now()<ESC>02ftct(" I expect to change the text 
"time.now" but it simply positions the cursor on the "w" as if I had 
not typed "c"  Is there some way to get the expected behavior outside 
of bash?  Note that the "c" command does work with single-keystroke 
motions, for instance "ce" or even with number modifier, "c2e"

my ~/.inputrc looks like this:

set editing-mode vi
set keymap vi

I get the same behavior in psql or using rlwrap.  I have tried this in 
several different terminals (terminator, xterm, cygwin-rxvt), using 
cygwin on windows and also on debian lenny (dpkg output below)
