Alternative special terminal handling
Alternative special terminal handling

1. the dot register preservation is g: only

I don't see the point of maintaining it on a per buffer basis.

2. remapping of the terminal escape codes happens once.

This probably still breaks some terminals or some escape sequences we
don't remap, but at least this is not worse then the original solution.

3. fixed typo in the setting name
