scanimage if supplied "--help" still tries to find devices

[Max Fuxjäger]

The scanimage command-line utility still tries to find devices when the user just wants to see the help text. Reproducible by:

1.: Terminal
2.: "scanimage --help"
3.: Utility blocks until it finished searching for devices

Expected outcome: Program should not run when --help option is used (or similar behaviour).

I just see now it says "experimental" a few times, but i never installed any unstable or non-recommended versions. Just the good ol' Software Center and preinstalled stuff.
