This is why I ask for an example natural user script where terminal
trashing occurs. The fate trashing thing (and its fix) made sense -
fate is meant to find regressions, sometimes expressed as fatal
signals. Even in non fate scenarios, ordinary signals that are within
FFmpeg's scope and not the shell's (non fatal) go to the handler,
which will restore the tty state once it receives sufficiently many
signals. Fatal signals should be very rare for non developers, and are
bugs with FFmpeg that need to be fixed as Nicolas points out.
Michael's point applies only to users and not developers; developers
can easily change their shell configuration.
