SHACL alternative paths get turned into nested structures unnecessarily

SHACLC parsing

shape ex:shape2 {
 targetNode = :WhatEver .
 ex:A|ex:B|ex:C datatype=xsd:integer .
}

produces

sh:path [ sh:alternativePath ( [ sh:alternativePath ( ex:A ex:B ) ] ex:C  )

which evaluates correctly but it could be sh:alternativePath ( ex:A ex:B ex:C ).

Printing SHACLC (and SPARQL) paths (PathWriter) puts in () over-cautiously to get (ex:A|ex:B)|ex:C.
