"--continue-at -" on new file no longer works

[jordanbrown0]

I did this

curl --upload-file myfile --continue-at - --user xxx:yyy ftp://host/nonexist

I expected the following

Upload new file.

The SIZE command is failing on a nonexistent target file, and that is causing the "continue-at" processing to fail.

This behavior is not clearly wrong, but it's a change.

Probably changed by PR #5957 .

Full disclosure: I work for Oracle on Solaris; this broke one of our tests.

Either the template didn't ask for it, or somehow I missed it, but what actually happened was:

cuttlefish# curl --upload-file /tmp/aaa --continue-at - --user xxx:yyy ftp://localhost/export/backup/aaa

Thanks.
