Hi ya
$ touch foobar
$ echo foobar | pax -rwds '/.*/&&/P' .
pax: Replacement name error foobar
This is because the resub() function that does the replacement,
upon a '&', attempts to copy data from the _pattern_ string
(above: ".*") instead of the input data "foobar". So, above, it
tries to copy 6 bytes (as in "foobar") from ".*" and obviously
fails.
Here is a patch:
