The extra character '\r' screws up the parsing because it was not
accounted for in the logic to recognize multi-line values and
indentation based block separation.
What do you think of a kind of piped filter as follows:
(define (call-with-input-file-eol-crlf->lf proc port)
(let* ((port-pair (pipe))
(input-port (match port-pair ((in . out) in)))
(output-port (match port-pair ((in . out) out))))
(letpar ((transcoder
(let loop ((line (get-line port)))
(unless (eof-object? line)
(write-line (string-trim-right line #\return) output-port)
(loop (get-line port)))
(flush-output-port output-port)))
(result (proc input-port)))
(close-output-port output-port)
(close-input-port input-port)
result)))
Then instead of calling (read-cabal port) I would call
(call-with-input-file-eol-crlf->lf read-cabal port).

Fede
