Description of problem:
When using the command-line ftp client, if you press Shift-Return, the
program will segfault.  Running gdb shows an infinite recursion within
readline.

It's very easy for my fingers to hit shift accidently when I press
return, I have found.






Version-Release number of selected component (if applicable):
readline-4.3-5

How reproducible:
Always

Steps to Reproduce:
1. ftp <return>
2. <shift-return>
3. watch it segfault
    

Actual Results:  flitterfly:bhelf% ftp
ftp> Segmentation fault (core dumped)
flitterfly:bhelf%


Expected Results:  flitterfly:bhelf% ftp
ftp>
ftp>
