TabCompletion is wierd

[neronmoon]

I'm trying to use psysh with Codeception. Here some code of my module.

<?php
$shellConfig = new Configuration([
    'requireSemicolons' => false,
    'historySize' => 100,
    'defaultIncludes' => [
        __DIR__ . '/../../_bootstrap.php',
    ],
]);

$shellConfig->addTabCompletionMatchers([
    new \Psy\TabCompletion\Matcher\VariablesMatcher(),
    new \Psy\TabCompletion\Matcher\ClassNamesMatcher(),
    new \Psy\TabCompletion\Matcher\ConstantsMatcher(),
    new \Psy\TabCompletion\Matcher\FunctionsMatcher(),
    new \Psy\TabCompletion\Matcher\ObjectMethodsMatcher(),
    new \Psy\TabCompletion\Matcher\ObjectAttributesMatcher(),
    new \Psy\TabCompletion\Matcher\KeywordsMatcher(),
    new \Psy\TabCompletion\Matcher\ClassAttributesMatcher(),
    new \Psy\TabCompletion\Matcher\ClassMethodsMatcher(),
]);
$shell = new Shell($shellConfig);
$shell->setScopeVariables(['I' => new AcceptanceTester()] + $context);
$shell->run();

Everything is fine, but tab completion goes very strange. When i type $I->[tab][tab] it shows one count of completions, but after some manipulations it's becomes OK. Example on img

See #292 and #167.

After defining a function

» psysh                                                                                  [13:52:55]
Psy Shell v0.7.2 (PHP 7.0.8-0ubuntu0.16.04.2 — cli) by Justin Hileman
>>> function signalToHierarchy($signal) {
...   $bracket = strpos($signal, '[');
...   if ($bracket === false) {
...     $first = $signal;
...     $second = false;
...   } else {
...     $first = substr($signal, 0, $bracket);
...     $second = substr($signal, $bracket, -1);
...   }
...   
...   var_dump($first, $second);
... }
=> null

When i type sig it tab-completes to signaltohierarchy, this seems odd because of:

1. function name to lower case
2. add extra space on the end

then when i press tab once more it just prints signaltohierarchy another time. So i end up with signaltohierarchy signaltohierarchy

this is weird too

function name to lower case

This is just PHP ¯\_(ツ)_/¯

>>> function fooBarBaz(){}
>>> get_defined_functions()['user']
=> [
     "composerrequired5d4e921bd47fcc9f760ee0015dd744a",
     "composer\autoload\includefile",
     "mb_ord",
     "mb_chr",
     "mb_scrub",
     "curry",
     "xcallable",
     "resolve",
     "dump",
     "psy\sh",
     "psy\debug",
     "psy\info",
     "psy\bin",
     "foobarbaz",
   ]

add extra space on the end

This (and the double completion) should be fixed soon!
