Hi again,

unar fails to extract files from a LHA archive embedded into an .exe
file. This time it's the Spear of Destiny demo available here:

http://users.skynet.be/bs366950/sodemo.zip

Steps to reproduce:

$ wget http://users.skynet.be/bs366950/sodemo.zip

$ unar sodemo.zip
sodemo.zip: Zip

  FILE_ID.DIZ  (415 B)... OK.
  SODEMO.EXE  (691765 B)... OK.
  INSTALL.CMD  (190 B)... OK.
Successfully extracted to "sodemo".

$ cd sodemo/

$ unar SODEMO.EXE
