-i: "Hunk #1 FAILED at 1." error

[greg-minshall]

hi (and many thanks for cram!). my .t file looks like

some backref errors

  $ cd ${TESTDIR}/../.. && ./sedcsv -f <(echo 's/(this)/\2/') < /dev/null

  $ cd ${TESTDIR}/../.. && ./sedcsv -f <(echo 's/(this)/\g{2}/') < /dev/null

  $ cd ${TESTDIR}/../.. && ./sedcsv -f <(echo 's/(this)/\g{1/') < /dev/null

and, my .t.err file is

some backref errors

  $ cd ${TESTDIR}/../.. && ./sedcsv -f <(echo 's/(this)/\2/') < /dev/null
  /dev/fd/63:1: backreference "\2" too high (1 max)
  [3]

  $ cd ${TESTDIR}/../.. && ./sedcsv -f <(echo 's/(this)/\g{2}/') < /dev/null
  /dev/fd/63:1: backreference "\2" too high (1 max)
  [3]

  $ cd ${TESTDIR}/../.. && ./sedcsv -f <(echo 's/(this)/\g{1/') < /dev/null
  /dev/fd/63:1: unable to find backreference closing ("}") in "\g{1"
  [3]

the cram run looks like
