commit 95c8aba6c9650ca6a301e352c8d9aa6c9e5fb475

[troff]: Demote `\D''` from error to warning.
* src/roff/troff/input.cpp (read_drawing_command): Demote diagnostic
thrown on empty drawing command escape sequence argument list from
error to warning in "missing" category. I can imagine someone
programmatically constructing a string to be passed to a `\D` escape
sequence; such a string might be empty.
