Add --update=none which is equivalent to the --no-clobber behavior from before coreutils 9.2. I.e. existing files are unconditionally skipped, and them not being replaced does not affect the exit status. * src/copy.h [enum Update_type]: A new type to support parameters to the --update command line option. [enum Interactive]: Add I_ALWAYS_SKIP. * src/copy.c: Treat I_ALWAYS_SKIP like I_ALWAYS_NO (-n), except that we don't fail when skipping. * src/system.h (emit_update_parameters_note): A new function to output the description of the new --update parameters. * src/cp.c (main): Parse --update arguments, ensuring that -n takes precedence if specified. (usage): Describe the new option. Also allude that -u is related in the -n description. * src/mv.c: Accept the new --update parameters and update usage() accordingly. * doc/coreutils.texi (cp invocation): Describe the new --update parameters. Also reference --update from the --no-clobber description. (mv invocation): Likewise. * tests/mv/update.sh: Test the new parameters. * NEWS: Mention the new feature. Addresses https://bugs.gnu.org/62572
