* Surprisingly, every escape sequence can also be used as an argumentIngo Schwarze2022-06-081-2/+96
| | | | | | | delimiter for an outer escape sequence, in which case the delimiting escape sequence retains its syntax but usually ignores its argument and loses its inherent effect. Add rudimentary support for this syntax quirk in order to improve parsing compatibility with groff.
