Backspace output after last column written

[Zsbán Ambrus]

Dear Marc,

You might remember our discussion about that a backspace output when
the cursor is after the last column, urxvt moves the cursor to the
last but one column.  You claimed not only that this conforms to
standards but also that most vt100 terminal emulators work this way:

I only have one new observation to this.  Gnu screen which is a
vt100-like terminal, also has backspaces wrapping from the beginning
of a line to the previous line, and it treats backspace from after the
last column the other way: it just moves the cursor to the last
column.  I tested this with at least Screen version 4.00.03jw4 (FAU)
2-May-06 (from debian lenny linux amd64).
