* use "AR_GNU" as the format name instead of AR_SVR4 (it's what everyone is going to call it anyway) * Simplify numeric parsing to unsigned (none of the numeric values should ever be negative); don't run off end of numeric fields. * Finish parsing the common header fields before the next I/O request (which might dump the contents) * Be smarter about format guessing and trimming filenames. * Most of the magic values are only used in one place, so just inline them. * Many more comments. * Be smarter about handling damaged entries; return something reasonable. * Call it a "filename table" instead of a "string table" * Update tests. Enable selection of 'ar', 'arbsd', and 'argnu' formats by name (this allows bsdtar to create ar format archives). The 'ar' writer still needs some work; it should reject entries that aren't regular files and should probably also strip leading paths from filenames.
