+    Everything after the first '=' character is passed as arguments to the command. The exact
+    interpretation depends on the command:
+    \li If the command only takes a single token as argument (e.g. a single string or numeric
+        value), everything after the '=' sign is parsed into a single token (e.g. see rows 2 and 3
+        of the following table).
+    \li In all other cases, the string after the '=' sign is parsed into argument tokens using the
+        config/console parser. In this case, quoted strings need to be quoted twice, once for the
+        shell and once for the config/console parser (e.g. see rows 4 and 5 of the following table).
+    \li If the option has no '=' character, the list of argument tokens will be empty (e.g. see row
+        1 of the following table)
+
+    Without these rules, multi-word string arguments would \e always have to be quoted twice (for
+    the shell and the config/console parser).
