bug#12398: 23.4; Disabling fringes causes term to garble certain text output. |

Steps to reproduce:
1. Disable fringes using Custom, such that this appears in the
custom-set-variables:
'(fringe-mode 0 nil (fringe))
2. Open a term buffer with `M-x term' (shell and ansi-term untested, sorry)
3. Run any program at all that will output a line that is longer
than the width of your terminal window. Good examples would be:
$ echo `seq 100`
or
$ cat some_file_with_long_lines.txt
Expected results:
The program runs and the output is displayed normally.
Actual results:
The program runs, but the output gets crammed all onto one line,
overlapping itself in a lossy way, and afterwards the prompt is lost and
any characters typed do not display. It is necessary to type C-l to
restore normal operation of the terminal.
Workaround:
Keeping the fringe only on the right-hand side seems to not trigger
this, eg, with this line in the .emacs:
(set-fringe-mode (cons 0 1))
Potentially relevant details:
Working in a *very* large frame, that has been split both horizontally
and vertically multiple times, resulting in $COLUMNS=100 for the
terminal.
