During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
These are caused by the “readline” perl extension. Under normal circumstances, it will move your cursor around when you click into the line that contains it. It tries hard not to do this at the wrong moment, but when running a program that doesn’t parse cursor movements or in some cases during rlogin sessions, it fails to detect this properly.
