OCD - undo some incorrect changes of non-typos from 4a0eed52f
Fix name mangle in Replicated.pm broken by e8c31aec and then by 4a0eed52
Apparently on_failure email flag affects the original author as well

Without this only the first committer who broke stuff will get an email
the rest of the breakage will remain silent

Extra paragraph dropped from 113e8d16 for some reason
