  * decode a percent-encoded C string with optional path normalization
  *
  * The buffer pointed to by @dst must be at least strlen(@src) bytes.
  * Decoding stops at the first character from @src that decodes to null.
  *
- * Path normalization will remove redundant slashes and slash+dot sequences,
+
- * as well as removing path components when slash+dot+dot is found. It will
+
- * keep the root slash (if one was present) and will stop normalization
+
- * at the first questionmark found (so query parameters won't be normalized).
