Accept more word delimiters when updating hooks
Accept more word delimiters when updating hooks

When updating container names in hook files during a container clone,
we substitute the new container name for the old any time the old name
shows up as a separate word.  This patch adds the four characters
'.,_-' as additional delimiters.
