+fix handling of special symbols in file operations.
+
+Path fixes at least following cases:
+  - attempt to enter directory named '#'
+  - attempt to open file named '#'
+  - attempt to dereference link named '#'
+  - attempt to chown file / dir named '#'
+
+The fix is basically following mechanical conversion:
+---    curl_easy_setopt_or_die(ftpfs.connection, CURLOPT_URL, something);
++++    something_uri = path_to_uri(something);
++++    curl_easy_setopt_or_die(ftpfs.connection, CURLOPT_URL, something_uri);
+===    curl_easy_perform();
++++    free_uri(something_uri);
+
+What is not yet converted is ftp hostname.
