[Lzip-bug] lzip support in file(1)/magic(5)

[Jan Engelhardt]

Hi,


wanting to let you know that the following patch has been submitted to 
the file(1) maintainer.

>From it, you can grab the lzip-specific mgc bits (just the four lines to 
Magdir/compress) and put it as a standalone file into the lzip software 
distribution if you like.


thanks,
Jan
