Johannes Schindelin 775477aa1d Teach import-tars about GNU tar's @LongLink extension. This extension allows GNU tar to process file names in excess of the 100 characters defined by the original tar standard. It does this by faking a file, named '././@LongLink' containing the true file name, and then adding the file with a truncated name. The idea is that tar without this extension will write out a file with the long file name, and write the contents into a file with truncated name. Unfortunately, GNU tar does a lousy job at times. When truncating results in a _directory_ name, it will happily use _that_ as a truncated name for the file. An example where this actually happens is gcc-4.1.2, where the full path of the file WeThrowThisExceptionHelper.java truncates _exactly_ before the basename. So, we have to support that ad-hoc extension. This bug was noticed by Chris Riddoch on IRC. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Shawn O.
