One of the users of my Debian tar packages reports that --transform only
works on symlinks during extraction, not on creation or listing. A
quick review of the info doc didn't suggest any reason for that to be
intentional?

Package: tar
Version: 1.19-1
Severity: normal
tar's --transform option seems to apply to symlink targets when
extracting an archive, but not when creating or listing one. (I
haven't checked other operations.)
