Description of problem:
I noticed this (presumably quite rare and subtle) bug when doing

pstree -lpn|less

in the terminal emulator "screen", running in gnome-terminal.
Basically sometimes when you output a particular character sequence
gnome-terminal spuriously adds an indent. I have verified that it's
not a screen bug by stracing screen using

strace -s 65536 -o screen.strace -e trace=write -p $PID_OF_ACTIVE_SCREEN

and the output is identical when the bug occurs and when the bug does
not occur (remember, it's pretty random). So it can't possibly be a
screen bug.

Note that this seems to be a timing-influenced bug (thread bug
perhaps?) so it might not occur on a faster machine. My machine is an
Athlon XP 1800. (Indeed the only reason why screen triggers this might
be that screen slows the catting down a little.)

Version-Release number of selected component (if applicable):
gnome-terminal-2.6.0-2

How reproducible:
Sometimes

Steps to Reproduce:
1. Download attached test file
2. Start gnome-terminal
3. Start screen
4. Type "cat bug"
5. As the bug is intermittent, you may need to try again a few times
before you see it.

Actual Results:  The xinetd line is indented, like this:

        ├─sshd(2154)
        ├       
├─xinetd(2169)───fam(4803)
        ├─ntpd(2184)


Expected Results:          ├─sshd(2154)
        ├─xinetd(2169)───fam(4803)
        ├─ntpd(2184)


Additional info:

(At first I thought that someone had hacked my box and was (bizarrely)
using my machine as an xinetd server. Look at the bogus output above -
you can see why I was worried!)
