Prevents terminal inconsistencies with \e[0A \e[0B \e[0C \e[0D etc. Applies the same guard to CursorUp/Down/Forward/Backward/NextLine/PreviousLine. Fixes spectreconsole#2076

ANSI terminals handle this inconsistently.
Most of them default to treating a 0 movement as a default value, and the default is 1.
