bug#64686: 30.0.50; Tar mode @PaxHeader bug

[Devon Sean McCullough]

$ wget 
https://f-droid.org/repo/com.simplemobiletools.voicerecorder_36_src.tar.gz
$ emacs --no-init-file --no-site-file 
com.simplemobiletools.voicerecorder_36_src.tar.gz

should show something like the output of

$ tar -tvz < com.simplemobiletools.voicerecorder_36_src.tar.gz

instead of spurious ././@PaxHeader lines
interleaved with truncated long file names.

        Peace
