Kenneth Benzie (Benie) ff87027cf7 Fix a long standing issue with fresh_almostontop() ...

Up till now setting the `-a` flag of the `prompt_fresh_setup` theme
resulted in duplicate prompts being printed to the terminal. The first,
the interactive prompt with syntax highlighting, and a second after a
call to the `clear` command without syntax highlighting. This patch
replaces the old implementation with one which does not use `clear`.
Instead it queries the terminal for the current cursor position, then
uses this to move to the bottom of the terminal, print a number of new
lines to move the stale command output off screen, and finally move
almost back to the top ready for the invoked command to print it's
output.
