I use back-tick `. For nested, it becomes `` or ````. For twice nested and I'm writing a shell script with ` instead of $( .. ) It's ```````` (I'm an emacs user, I need all the control characters :)
I also use backticks, and in 99.9% of cases it works like a charm. But then one day you paste a large file, and the gates of hell open. Tmux randomly opens windows, kills sessions, and launches nuclear missiles while processing all the backticks in the text.
Yeah, that's true. Tho for large pastes, I generally only do that in a locally running GUI emacs. For remote, I'll assemble the file and then scp.
Even without tmux, this can be an issue - a long time ago I was using the X windows "drag the selection" middle mouse button action and accidentally let go of the button while the cursor was over an emacs text window - I sent my first email to some big listserv I subscribed to consisting of weird fragments from the log file I was trying to paste.a
