Set terminal title automatically [OpenBSD/ksh]
This patch sets the terminal title when the DISPLAY variable is set.
When a command is invoked, the terminal title will be set to:
"$ full -command -line"
When the command execution is finished, the terminal title will be
reset to:
"$ ksh (/current/path)"
