I've noticed square brackets in the "gutters" of a Terminal window when editing files in emacs. The brackets are on either side of the screen and go away if I force a window update by either resizing it or a ctrl-l. I'd like to figure out how to turn the feature off.
Here I've just made some edits to the lines starting with 'a.x' and 'or'.
Here's a zoomed out view showing the brackets in both the right and left hand sides of the screen.
- looked at the preferences for Terminal
- looked at my emacs configuration
- built a new version of emacs ( 25.4 )
- found an emacs feature new in 22.x called fringes
- set-fringe-mode off had no effect in 24.5 or 24.4
- skipped local initialization (-q)
- skipped all initialization (-Q)
I fired up vi (vim 7.3) and lo and behold, the square brackets show up in the gutters there too! So not an emacs problem more than likely.
I'm running OS X 10.11 El Capitan on a mid 2014 MBP and the Terminal version number is 2.6 (361). The change bars show up in text editors running within Terminal whenever a return occurs on a line with or without existing text and go away on a redraw.
I'm hoping someone will see this and know how to turn it off.
