Hiho:
- Save the attached file as 'testfile'
- Create a 125x23 M-x term window (same problem with 80x23) .
- At the shell prompt, run 'vi testfile' with the attached file
- Type C-d to tell vi to scroll down
- The first line will contain "12" and you'll see that the line for "22" is
blank. That blank line is the problem.
The problem seems to be in term-delete-lines (or the argument passed to it
from the `M' case of term-handle-ansi-escape). In edebug these lines from
term-delete-lines move point down one too few lines and then insert a
newline which wipes out "22":
(term-down (- term-scroll-end save-current-row lines))
(term-insert-char ?\n lines)
I'm using Debian GNU/Linux unstable.
Here's a snippet of M-xterm log (from term-start-output-log); I replaced
ESC characters with '^[' and Ctrl-M with '^M'. It seems like the
processing of '^[[11M' is the problem:
^[[1;22r^[[1;1H^[[11M^[[1;23r^[[12;1H23^M
24^M
25^M
26^M
27^M
28^M
29^M
30^M
31^M
32^M
33^[[1;1H
Thanks!
