Patch Level: 21
Release Status: release

Description:
Hi. Everytime i use set -n it, alone or with an argument, it kills my shell.  
All the shell will do after this is entered is redisplay the 
PS1 prompt after I press return.  Even exit doesn't work, i have 
to use ^D to close the terminal window. (I use rxvt v2.7.5 terminal windows in 
X.)

Repeat-By:
        Open an rxvt window.  Enter set -n.
