Subject: [PATCH] Reader: resolve BSD-variant file names before checking for
 symbol tables

Darwin's `ar(1)` writes BSD-variant archives and treats file names
containing exactly 16 characters as long file names; this causes it to
write sorted symbol tables with the file name `#1/16`, which only
becomes `__.SYMDEF SORTED` after long file names have been resolved.
Parse the file name before checking whether it is indicative of the
archive member being a symbol table.

Fixes #22.
