+- GNU eqn converts some operators to special characters, for example,
+  input HYPHEN-MINUS becomes output \(mi, unless it is part of a
+  quoted word.  mandoc(1) only does this when the operator is
+  surrounded by blanks, not when it is part of an unquoted word.
+  Also, check whether there are more such cases (e.g., +?).
