In reference to some comments about shell aliases to change the title

This occurs because xterm and shelltool use different escape sequences to
set the title string.  Xterm uses

	^[]2;yourtexthere^G

whereas SunView shelltool uses

	^[]lyourtexthere^[\

By coincidence, X11R3 and earlier versions of xterm would accept a string
similar to SunView's.  You could set an xterm with the same sequence,
except that the string would be terminated by ESC instead of ESC-backslash.
So, if you programmed your shell to emit

	^[]lyourtexthere^[

to set the title string for xterm, and then moved over a SunView shelltool,
the shelltool would "hang" building up the title string.  It would stay
"hung" until it got ESC-backslash.

This happened to me once.  The resulting title string was quite amusing
once I got the shelltool out of that mode.  Now my shells base their
title-setting sequences on the terminal type.
