I didn’t notice that my editor trimmed this trailing whitespace. I’m sorry.
Reverted on branch.

I did this to reduce output in the .result file. Fixed:

+-- test-run result file version 2
+net_box = require('net.box')
+ | ---
+ | ...
+msgpack = require('msgpack')
+ | ---
+ | ...
+urilib = require('uri')
+ | ---
+ | ...
+
+IPROTO_REQUEST_TYPE = 0x00
+ | ---
+ | ...
+IPROTO_PREPARE      = 13
+ | ---
+ | ...
+IPROTO_SQL_TEXT     = 0x40
+ | ---
+ | ...
+IPROTO_STMT_ID      = 0x43
+ | ---
+ | ...
+
+box.schema.user.grant('guest', 'read, write, execute', 'universe')
