bug#8763: terminal-emulator mode confines output to 80 columns

[bugreport.emacs.jog]

If emacs is in terminal-mode, it seems to constrain some tools to 80 columns of output.  Running "watch" inside an emacs terminal wraps the line:

emacs -nw --eval='(terminal-emulator "*echo nested inside watch*" "watch" '"'"'("--interval" "3600" "echo xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"))'

The problem is not the watch command, because the following will properly show 85 x's on one line (outside of emacs):

watch --interval 3600 echo xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Note that the following will correctly show 85 x's on one line (suggesting that the problem emacs does not have this problem with all tools):

emacs -nw --eval='(terminal-emulator "*echo only*" "echo" '"'"'("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"))'

This bug is still present in terminal.el, but doesn't happen with
term.el.  Since terminal.el is now marked obsolete, and there hasn't
been any movement on this bug for a long time, I'm closing as wontfix.
