Errors in special buffers

[tokebe]

Hey, thanks for this great plugin! Very useful in my day-to-day, I'm surprised it hasn't gathered more attention :D

Using nvim-dap-view, whenever I enter the repl or console buffers I get errors which repeat on each keystroke.

Expand for error message

I'm not well-versed enough in nvim logic/ftmemo's design to diagnose further, but perhaps a configuration option to ignore certain filetypes when running the autocommand may prevent this? There are plenty of special, plugin-specific filetypes that no reasonable user would need to change / expect ftmemo to remember.
