[QA] config setting filesystem_check_changes is unclear

https://github.com/owncloud/docs/blob/master/modules/admin_manual/pages/configuration/server/config_sample_php_parameters.adoc#define-how-often-filesystem-changes-are-detected

Define how often filesystem changes are detected

Specifies how often the local filesystem (the ownCloud data/ directory, and NFS mounts in data/) is checked for changes made outside ownCloud. This does not apply to external storages.

→ Never check the filesystem for outside changes, provides a performance increase when it’s certain that no changes are made directly to the filesystem

→ Check each file or folder at most once per request, recommended for general use if outside changes might happen.
Code Sample

'filesystem_check_changes' => 0,

It is unclear which of the two arrow items is illustrated by the code sample. Expected behaviour: settings are shown for both arrow items.
