communityconfiguration-editor-client-file-bug and communityconfiguration-editor-client-file-bug-link-content are a pair of "lego" messages. They are concatenated in run time.
The MediaWiki convention is to avoid lego messages because they cannot be reliably translated to many languages with different word order, etc.
If the message needs simple markup, it can be inserted into one message. If it needs complex markup, the complex markup parts should be inserted into the message using parameters ($1, $2, etc.)
