Re: [Jed-users-l] Turning off auto-wrap

[Doug Kramer <doog@xxxxxxxxxx>]

This works to stop wrap in a *.txt file, but only if I call toggle_wrapmode
*after* opening the file.
I want to turn off wrapmode as a default.

If I try to set "toggle_wrapmode;" as a default in .jedrc, it has no effect
on wrap within a *.txt file that I subsequently open.

Is there a way to modify this so I can turn off wrapmode in .jedrc as a
default for all files that I subsequently open (without having to call
toggle_wrapmode after opening the file)?
