Hello:

For some reason, when public-inbox-mda reindexes the repository
past-delivery, it creates some files as 0660, even though umask is
specifically set to 0002:

$ ls -al public-inbox/xapian15/

Since the daemon is running as user "publicinbox", this causes the web
interface to break due to not being able to access the index.
