+-A Bash escaped string. The strings are wrapped in @$\'...\'@ if any
+-bytes within them must be escaped; otherwise, they are left as is.
+-Newlines and other control characters are represented as ANSI escape
+-sequences. High bytes are represented as hex codes. Thus Bash escaped
+-strings will always fit on one line and never contain non-ASCII bytes.
