ConEmu OSC Codes

[Jan200101]

ConEmu make use of OSC 9 to implement a few terminal specific commands that may or may not be worth emulating.
Because OSC 9 is also used by iTerm2 it might be worth implementing undesired functions as a noop, but thats to be discussed

Commands:

• 1 sleep
• 2 show GUI message box
• 3 change window title
  • probably just change_window_title will need to test
• 4
  • sets progress state, useful for informing the user how far a process is along
  • parsing added by terminal: implement support for ConEmu OSC 9 progress report #3099, no frontend is capable of using it yet
• 5 wait for Enter, Space or Esc input
• 6 Execute a GuiMacro
  • unsuited for GhosTTY
• 7 run some process
  • potential for priviledge escalation, unsuited for GhosTTY
• 8 output of environment variable
  • potential for data exiltration, unsuited for GhosTTY
• 9 inform terminal about shell current working directory
  • appears to just be OSC 7 without fhe file:// segment
• 10 turn on or off xterm emulation
  • not worth emulating?
• 11 just a "comment"
• 12 "Let ConEmu treat current cursor position as prompt start."
