rewrite() renames the members of a tar blob, but the TarInfo objects carried over from the input still hold the pax "path" supplement that was recorded for the original name. Re-serialization (tf_out.addfile()) uses the pax supplement with higher precedence than what's in the base header's name filed, so for member names exceeding the 100 character ustar limit the rewrite silently has no effect and the original name is written back. Drop the stale "path" supplement after renaming a member. tf_out.addfile() then builds a rewritten, up-to-date supplement from the name field if it needs one.
