The USTAR format says:
<<<
Implementors should be aware that the previous file format did not include
a mechanism to archive directory type files.
For this reason, the convention of using a filename ending with
<slash> was adopted to specify a directory on the archive.
>>>
In light of this suggestion, make the following changes:
* Writer.WriteHeader refuses to encode a header where a file that
is obviously a file-type has a trailing slash in the name.
* formatter.formatString avoids encoding a trailing slash in the event
that the string is truncated (the full string will be encoded elsewhere,
so stripping the slash is safe).
* Reader.Next treats a TypeRegA (which is the zero value of Typeflag)
as a TypeDir if the name has a trailing slash.
