      Description

      While running the tika detector on some old Quattro Pro for DOS spreadsheets, I noticed these files are identified as "application/x-123" (Lotus 1-2-3). This happens because the magic patterns for for "application/x-123" only covers the first 4 bytes, which for one of them creates a collision with the Quattro Pro for DOS magic pattern. I've created a patch which includes more specific mimetype definitions and magic patterns for both Lotus 1-2-3 and Quattro Pro. Patch is on its way!
