| Hello, list,

|     alias jobcmd 'echo -n "\033]2;\!#:q\007"'

| prints the job to the xterm title, as desired. But I digress.
| When I use `ls`, as aliased above, the string "0m" is printed before the fi=

| file in the directory. I've found that replacing the system's ls by the bui=

| ls-F solves the issue, but I'm curious as to what might be happening.
| Note that I'm using GNU's ls, as is standard in linux operating systems.

I have not been able to reproduce this with xterm. What terminal are you
using? What does telltc print?
