Doc Text Cause: switch the scp utility from SCP to SFTP protocol

Consequence: copying file to itself using different hostname effectively truncates the file

Workaround (if any): First, there is no reason to copy a file to itself.
If you really have to do it, you may explicitly fallback to old protocol using -O, though it's not recommended.

Result: Self-copying file will not damage it

.SCP empties files copied to themselves

Because of the switch of the `scp` utility from the SCP to the more secure SFTP protocol, copying a file from a location to the same location erases file content. To work around this problem, do not copy files to a destination that is the same as the source location. If your scenario requires this, you can force `scp` to use the old protocol by using the `-O` option. Note, however, that the SCP protocol is less secure.

.`scp` empties files copied to themselves when a specific syntax is used

The `scp` utility changed from the Secure copy protocol (SCP) to the more secure SSH file transfer protocol (SFTP) protocol. Consequently, copying a file from a location to the same location erases the file content. The following syntax is affected by the problem:

`scp localhost:/myfile localhost:/myfile`

To work around this problem, do not copy files to a destination that is the same as the source location using this syntax.

The problem has been fixed for the following syntaxes:
`scp /myfile localhost:/myfile`
`scp localhost:~/myfile ~/myfile`

NOTE: If your scenario requires the less secure SCP protocol, you can force its usage by adding the `-O` option to the `scp` command, for example, `scp -O localhost:/myfile localhost:/myfile`.
