This is a change in behavior from 1.16.1, which does not yet appear in the
Changelog.

I was bitten by this change during my attempt to rebuild some standard
software from is distribution tar archive.  I would *never* use -P when
extracting someone else's tar archive into my file system, but this change
seems to *require* that I do in order to correctly extract the archive (or,
manually fix all broken symbolic links by hand).

This doesn't seem appropriate, and is going to bite a lot of software
distributors and builders.
