[x265] nit: description for CLI option --[no-]lossless may need reformatting

[Mario *LigH* Rohkrämer]

Long line may need a manual break:

+----
    --[no-]lossless               Enable lossless mode, bypassing  
transform, quantization and in-loop filters globally. Default
disabled
+----

-- 

Fun and success!
