otherwise repo names containing "@" in them were causing the @foo part
to be interpolated (as empty of course) instead of being taken literally
reported by silvio dot fricke at googlemail
(and in one other place it needs to be defined earlier)
I never caught this because in my testing those error conditions --

- get_rights_and_owner normalises its arg1 by stripping .git if
supplied, then sets the variable "repo" to the result as a side
effect
- new "help" adc with some default text but main purpose is to allow
site local help text
- other adc's refer to 'help' adc when appropriate
- 'undelete' renamed to 'restore'; that's what the KDE "trashcan"
program calls that operation
- minor typo in sample script in documentation
- main adc doc points to contrib/adc/repo-deletion.README now
