#2265 tar extended pax header detection is not worked.

[Vladimir Surguchev]

7z support tar long (> 100) filenames extraction from extebded pax heder.
But pax header detection works not perfect.
There is link to farmanager arclite discussion for one missed case (with patch):
https://bugs.farmanager.com/view.php?id=3806

PS: is check item.Name is not required? aybe item.LinkFlag (x/X/g) is enough.

Is it possible to correct typos in my ticket?

Fix

CPP\7zip\Archive\Tar\TarIn.cpp

replace

  if (item.Name.IsPrefixedBy("PaxHeader/")
         || item.Name.Find("PaxHeaders.4467/") >= 0)

by
~~~
if (item.Name.IsPrefixedBy("PaxHeader/")
|| item.Name.IsPrefixedBy("PaxHeaders.X/")
|| item.Name.IsPrefixedBy("./PaxHeaders.X/")
|| item.Name.Find("PaxHeaders.4467/") >= 0)
~~~~~~

Probably it was fixed in latest version 21.01 already.
