The listbox comes up as wide as my screen, but no wider. Seems like
acceptable behavior to me.

Yes, but the width of 20 is still a pain. I grew annoyed enough to
track this down and fix it when I had a help document for 'lag()' in my
local package as well as the one in the 'stats' package. When I entered
at the R prompt, I'd get a menu offering me a choice of which document
to show, but the strings identifying the choices were so truncated that
it was difficult to know which one was which. 20 characters is just too
Do you not agree that sending "width = 0" and letting Tk handle it
automagically is better than what's in there now?
