Function scanPgpCont

plumbing/object/commit_scanner.go:266–268

scanPgpCont accumulates continuation lines for a signature header. Continuations strip exactly one leading space, mirroring upstream's `line + 1` (commit.c:1509). The first non-continuation line is pushed back so scanHeaders can dispatch it. Repeat occurrences of the same signature header land back

(s *commitScanner)

// header land back here and concatenate, matching upstream's
// parse_buffer_signed_by_header (commit.c:1186).
func scanPgpCont(s *commitScanner) (commitState, error) {
	return continuationCont(s, &s.c.PGPSignature, scanPgpCont)
}

func continuationCont(s *commitScanner, dst *string, self commitState) (commitState, error) {
	line, err := s.readLine()
