These changes enable tar.vim to keep permissions of files that were
edited intact instead of replacing them with the default permissions.
The major change for this is switching from "tar -OPxf", which reads out
the contents of the selected file from an tar archive to stdout to
"tar -pPxf" which extracts the selected file to the current directory
with permissions intact
This requirs the temporary directory to be created earlier.
