I've been experimenting with uxrvt recently as a potential replacement for gnome-terminal. One problem I'm having with it is inserting continuation characters when a line wraps around. This is a problem with long URL's (e.g. password reset keys) as the URL is broken up and an extra character included.
How can I disable this behaviour?
Doesn't do this for me.
echo -n abc def ghi jkl mno pqr stu vwx yza bcd efg hji; echo -n abc def ghi jkl mno pqr stu vwx yza bcd efg hji; echo abc def ghi jkl mno pqr stu vwx yza bcd efg hji
results in just simple wrapped output, with no "+". I checked my ~/.config/app-defaults/URxvt to see if I had given any special setting for this, but nothing looks relevant. And moving that aside and starting a new terminal gives me same behavior.
I do see + at the start of wrapped lines in vim. Similarly, a "@" at the end of wrapped lines in less. But I assume you're just talking about wrapped lines at the shell prompt.
Do you still see this is you temporarily move aside all your .bashrc-and-friends files and start a new terminal?
Are you sure it's urxvt that's adding the "+" signs? I'm taking a wild guess here, and gonna assume you use mutt (because I use urxvt and had that issue with mutt).
Add set markers = no to your muttrc.
TERMset toTERM=rxvt-unicode? What window manager are you using - gnome? i know xmonad has acrlf offoption specifically related to copying from the terminal, but not sure if this is what's driving your problem or if there is a related fix in whatever WM you're using.
