Log:
Certain filenames between 245 and 255 characters long would cause an
internal error if pax extended attributes were being generated. Being
< 255 characters, the first-pass path editing (to generate a
ustar-compatible name for the main entry) wouldn't occur, and the
second-pass path editing (to generate a ustar name for the pax
attributes entry) assumed the input was already < 245 chars.
The core problem here was using an abbreviated algorithm for the
second pass that relied on the first pass having already run. The
rewritten code is much simpler: It just uses the full path-shortening
algorithm for building both ustar pathnames. This way, the second
ustar pathname will always be short enough.
