From: Victoria Dye <vdye@xxxxxxxxxx>
Update 'git diagnose' to *not* include '.git/' directory contents by
default, instead requiring specification of a '--all' option to include it.
While helpful for debugging, the archived '.git/' directory contents may be
sensitive, as they can be used to reconstruct an entire repository.
To guard against users inadvertently including this information in
diagnostics and sharing it (e.g., with the mailing list), '.git/' directory
contents will only be included if '--all' is specified.

+ This additional data may be sensitive; a user can reconstruct the full
