Hidden option on blih

[AlexisAuriac]

I noticed the delete option on repository isn't listed in the usage but is coded and works. Some interesting lines:

• line 117: Definition of the repo_delete function
• line 160: Definition of the usage_repository function
• line 193: Condition to call the repo_delete function
