Interpet or drop terminal control sequences

Recorded sessions may include control sequences that can be ignored. For example, tmux sets a title definition. This causes the title string to be included in the recording output, duplicating the shell prompt effectively.

This is likely to be fixed in the terminal emulator we're using.
