SPLIT in template strings doesn't current support splitting on new lines. I have a use case where I have multiple lines per cell in a CSV (as a list of synonyms for each term) and so I'd like to split on newlines. Ideally I would like to allow SPLIT to support regexes but there isn't a clear, non-risky way of doing this without possibly breaking backwards compatibility.

After some discussion with @jamesaoverton on the OBO Slack channel we came to the conclusion that we would just explicitly support new line characters in SPLIT.

Note: In the template string the slash character must be escaped so that it is preserved. Thus SPLIT=\\n works but SPLIT=\n will not.
