Re: [PATCH] install-sh: prevent existing directories from being chown'ed

    https://lists.gnu.org/archive/html/automake-patches/2018-03/msg00003.html

the --help message already says that chown applies to "installed files",
and an existing directory is not "installed", I didn't think it needed
any additional doc. --thanks, karl.
