Fix broken terminal output

[ssvine]

This pull request fixes this issue.

There are a number of problems with terminal output:

• Terminal output is broken when a command is failed (SCP commands)
• If panels are shown, then executing a command causes terminal to clear the previous output. This is very annoying. Far does not clear terminal under the same conditions
• If Far is working with ConEmu console emulator in BufferHeight mode ON, then executing command is not showing: for example, if pwd is entered, then a line $ pwd is not shown.

This problems are fixed with this pull request.
