+/// Add a mapping. Unlike @ref do_map this copies the {map} argument, so

+///
+/// @param map  C-string containing the arguments of the map/abbrev command,
+///             i.e. everything except the initial `:[X][nore]map`.
+/// @param mode  Bitflags representing the mode in which to set the mapping.
+///              See @ref get_map_mode.
+/// @param nore  If true, make a non-recursive mapping.
