Function parse_porcelain 

pub fn parse_porcelain(text: &str) -> Vec<WorktreeRecord>

Parse porcelain records from attribute lines. The separator is the caller’s: \n for --porcelain, \0 for --porcelain -z. A blank attribute ends a record.

Unknown attributes are ignored rather than refused: git adds them over time, and a new attribute is not a reason to stop answering questions about the ones that exist.
