There are two types of plain text - that which requires explicit
line-breaking, and that which does not. This is a case where a
non-linguistic tailoring is required.
TUS has a whole section on the issue, namely TUS 7.0.0 Section 5.8.
One thing that is missing is mention of the convention that a single
newline character (or CRLF pair) is a line break whereas a doubled
newline character denotes a paragraph break.
