I'm wanting to prepend one line onto each future line, each of which should be shipped separately to Logstash. I haven't been able to find anything that looked like this in the documentation.

The "log" that I'm parsing is broken into sections, i.e.:  
servername 1  
line 1  
line 2  
...  
servername 2  
line 1  
line 2  
...  
What I'd like to do is have the server name prepended to each of the following lines, until another matching servername "start" line is found. To be clear, I want each of the other lines to be a separate message into Logstash, but each should contain the server name that preceded the section.  
Is carrying forward a variable like this something that multiline can already do, or would this be an opportunity for an enhancement request?

You could use the multiline feature in Filebeat to group the related logs lines together into a single event. Then send the data to Logstash where you would apply a grok filter to parse the server name from the message, then apply a [split filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-split.html) to break the event apart.
