file doesn't recognise lzma archives with higher compression

[Ken Sharp]

$ lzma -fqqkz Hello\ world.txt ; file Hello\ world.txt.lzma ; lzma -fqqkz9 Hello\ world.txt ; file Hello\ world.txt.lzma
Hello world.txt.lzma: LZMA compressed data, streamed
Hello world.txt.lzma: data

File doesn't recognise lzma archives when -9 is used for compression.
