Description Eric Eisenhart 2004-05-20 22:13:49 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6)
Gecko/20040220 Firefox/0.8

Description of problem:
http://vt100.net/docs/vt100-ug/chapter3.html#CUP

We have an application on another unix that sends something like:
ESC [ 10 H
instead of
ESC [ 10 ; 0 H
or:
ESC [ 10 ; H
(spaces add for clarity)

That is, it's assuming that when the second parameter is 0 (start of
line), it can leave it out entirely, including the semicolon.

xterm, konsole, the linux terminal and other programs agree that "ESC
[ Pn H" is the same as "ESC [ Pn ; H".

Version-Release number of selected component (if applicable):
gnome-terminal-2.2.2-1

How reproducible:
Always

Steps to Reproduce:
1. run gnome-terminal
2. cat sample.problem.txt (attached)
    

Actual Results:  Roughly:
foo
barbaz


Expected Results:  foo
bar


baz

that is, I expect it to look the same as if step one was "run xterm"

Additional info:

I will attach my sample.problem.txt file as well as a screenshot of
the incorrect output and the correct output.
