Correct, exclude patterns are globs, and there's no glob that matches
files whose names consist entirely of digits. It would be nice if rsync
supported regular expressions for exclude patterns. But in this case,
there is a glob for files whose names do not consist entirely of digits:
*[!0-9]* . You can include these files and then exclude all (other)
files. The options to do this throughout the copy would be:

To get the rules to apply only in ~/News, anchor the patterns and use
the ** syntax to match anything below ~/News. The patterns are matched
against files' full paths from ~, but the first pattern accepts a
non-numeric character only in the basename because the final * cannot
