xterm wrongly handles Unicode on the prompt when printing text

[Dominik George]

Binary package hint: xterm

xterm misinterpretes some characters and writes junk text to the terminal under the followign conditions:

1. The prompt contains special charachters, in this test case german umlauts
2. The text printed from a command (shell built-in, program, script, etc.) does not end with a line break

Steps to reproduce:

Start xterm or any terminal emulator relying on it (e.g. gnome-terminal), then create or cd into a directory containing an umlaut (e.g. Ü11). Run a command that generates a one-line output of text, e.g. "echo -n Hello".

Expecgted behaviour: The output text is printed in front of the next line's command line prompt with the input mark behind the prompt

Current behaviour: Text is not printed, instead, parts of the prompt are printed behind it and after the input mark

Sorry, Launchpad Edge crashed while filing the report, so it accidentally got through twice.
