unrecognized option --globals-backup with PHPUnit 6.0.5

[bcremer]

The CLI-Option globals-backup is documented in the help output but does not exists.

Steps to reproduce:

$ phpunit --version
#!/usr/bin/env php
PHPUnit 6.0.5 by Sebastian Bergmann and contributors.

$ phpunit -h | grep globals
  --globals-backup            Backup and restore $GLOBALS for each test.

$ phpunit --globals-backup 
#!/usr/bin/env php
PHPUnit 6.0.5 by Sebastian Bergmann and contributors.

unrecognized option --globals-backup

Related to #2190.

Edit: Found the broken line here: 3320e0c#diff-cd488f091cbf795c2aeeb97f5342dec8R39 (Typo backup-globals vs 'globals-backup)
