I would like to provide a way to preview the effects of pathname edits,
but pattern selection has to happen against the unedited path, so it
seems that we have to show people the unedited path to help in
designing selection patterns.
In addition to a number of bug fixes and minor changes:
* --numeric-owner (ignore user/group names on create and extract)
* -S (sparsify files on extraction)
* -s (regex filename substitutions)
* Use new libarchive 'linkify' to get correct hardlink handling for
both old and new cpio formats
* Rework 'copy' test to be insensitive to readdir() filename ordering
Most of the credit for this work goes to Joerg Sonnenberger, who
has been duplicating features from NetBSD's 'pax' program.
