The same key appears multiple times in a bundle file.  If each
messages should be different or should be used independently,
then each messages should have different keys.  If the message
is used at a single place, then multiple occurrences should be
unified.

This duplication means that it's not known at runtime which
message will be used.  This issue also increases translation
cost (time and effort).
