docs: correct the claim about counting a symlinked directory
GNU ls follows a symlink to a directory with or without a trailing slash, so
both forms count the packages correctly. Only -d lists the link itself.
The original claim came from a count taken where the path did not resolve at
all, and it reached the spec, the plan and two commit messages. The count was
always right; the reason given for it was not, and a comment that teaches the
next reader something false is worse than no comment.
Records the real trap in its place: ls aliased to a long format counts its
"total" header as a package.
