Description of EXIT CODE 25 in man page is not fully correct

[emanuele6]

I did this

curl.1 describes exit code 25 as:

       25     FTP  could  not STOR file. The server denied the STOR operation,
              used for FTP uploading.

Suggesting it is a FTP only error.

I expected the following

curl can return 25 if any upload fails (e.g. HTTP PUT):

$ cat .bashrc | curl -sST - -0 example.org
curl: (25) Chunky upload is not supported by HTTP 1.0

libcurl-errors.3 describes error 25 (CURLE_UPLOAD_FAILED) as:

       CURLE_UPLOAD_FAILED (25)
              Failed starting the upload. For FTP, the server typically denied
              the STOR command. The error buffer usually contains the server's
              explanation for this.
