Comment 1 for bug 1332822

I can reproduce this with the same version and OS as yours, using putty from Windows. When I change width (to Nx24 instead of 80*24) of putty window, I get prompt copied when I press arrow up:

mysql> mysql> show plugins;

Query just works when Enter is pressed. I am also not sure is it a problem caused/related to putty or TERM setting:

[root@centos openxs]# echo $TERM
xterm
[root@centos openxs]# mysql --version
mysql Ver 14.14 Distrib 5.6.17-66.0, for Linux (x86_64) using EditLine wrapper
[root@centos openxs]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m

[root@centos openxs]#

or mysql client itself.
