(can_* == can_read, can_write, and can_create)
See top of contrib/adc/adc.common-functions for more on this.
Note: the old style (calling get_rights_and_owner with $repo, then
checking $perm_read, $perm_write, etc.), will still work fine.
- 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
