* fs: add TerminalColorMode type * fs: add new config(flags) for TerminalColorMode * lib/terminal: use TerminalColorMode to determine how to handle colors * Add documentation for '--terminal-color-mode' * tree: remove obsolete --color replaced by global --color This changes the default behaviour of tree. It now displays colors by default instead of only displaying them when the flag -C/--color was active. Old behaviour (no color) can be achieved by setting --color to 'never'. Fixes: #6604
