tmux:
Dsbp, Enbp
Disable and enable bracketed paste. These are set automatically
if the XT capability is present.
I was curious what happens if i embed the user-proram bracketed-paste end
marker (\x1B[201~) in the X selection, as the terminal i use does
not protect itself from doing anything on the selection data
except changing any \n to \r. Actually
printf 'a\x03\x1b[201~echo du' > .T1
printf 'a\x1b[201~\x03echo du' > .T2
and then xclip .T[12] and then .. whatever. bash cannot be
"fooled", but the "a" is then invisible here
printf 'a\x1b[201~\x03echo du' > .T2
xclip .T2
echo du~
^pasted
-bash: cho: command not found
Dunno since when i can no longer copy-selection etc via tmux
without it actively changing what i want to copy! 'Thus that
printf stuff above. If that is what you meant :-(
