+ * @param[in]  w1       First tab-delimited part of the string to parse.

+ * @param[in]  w3       Third tab-delimited part of the string to parse.
+ * @param[in]  w4       Fourth tab-delimited part of the string to parse.
+ * @param[in]  start    Pointer to the beginning of the string inside buffer.
+ *                      This must point to the same buffer as `buffer`.
+ * @param[in]  buffer   Pointer to the buffer containing the script. For
+ *                      single-line mapflags not inside a script, this may be
+ *                      an empty (but initialized) single-character buffer.
+ * @param[in]  filepath Source file path.
+ * @param[out] retval   Pointer to return the success (EXIT_SUCCESS) or failure
+ *                      (EXIT_FAILURE) status. May be NULL.
+ * @return A pointer to the advanced buffer position.
