Fix RuntimeException when an Emacs buffer is modified

rubenrua · rubenrua · commit 7c019243435c · 2017-02-23T14:08:23.000+01:00
When an Emacs buffer is modified, by default Emacs automatically creates a
temporary symlink in the same directory as the file being edited (e.g. Controller.php):

```
.#Controller.php -&gt; user@host.12345:1296583136
```

where '12345' is Emacs' PID.

In this case Symfony breaks with a RuntimeException:

```
SplFileInfo::getMTime(): stat failed for ...Bundle/Controller/.#APIController.php
```

in
vendor/symfony/symfony/src/Symfony/Component/Config/Resource/DirectoryResource.php
at line 89

```
$newestMTime = max($file-&gt;getMTime(), $newestMTime);
```
