| Doc Text: |
Previously, the file utility did not contain a "magic" pattern for detection of files compressed using the LZMA algorithm. As a consequence, the file utility was unable to detect these files. This update adds the missing "magic" pattern, and LZMA compressed files are now detected as expected.

This can be fixed by backporting this magic pattern from file-5.07:
0 lelong 0x8000005d LZMA compressed data,
>5 lequad =0xffffffffffffffff streamed
>5 lequad !0xffffffffffffffff non-streamed, size %lld
!:mime application/x-lzma
