Description

Add support for customizing FTP transfer aborted status codes. GitHub PR #51.

This is connected with another PR I did a few months ago. We hit yet another FTP that returns some strange status code when prematurely closing a stream - this one returns 550.

This PR makes these status codes that should be treated as OK configurable with a default of 426 and 550 to handle such cases like the ones we've encountered.

P.S. Here is output from a curl -v --range 0-499 "ftp://user:pass@192.168.40.224/dir/file.mpg" --output - command:

...
> RETR file.mpg
< 125 Data connection already open; Transfer starting.

• Maxdownload = 500
• Getting file with size: 500
• Remembering we are in dir "dir/"
  > ABOR
  < 550 Data channel was closed by ABOR command from client.
• partial download completed, closing connection
  > QUIT
  < 226 ABOR command successful.
• Closing connection 0
  P.S.2 This happens on a "Microsoft FTP Service":

...
220 Microsoft FTP Service

This is from the curl log.
