[Bug 1339186] [NEW] Wrong version 1.00 of libmagic

[yannick.chevalier@gmail.com]

Public bug reported:

The version 1.0.0 of libmagic distributed in the git of "file" (http://www.darwinsys.com/file) differs slightly from the one shipped by ubuntu (which is also versioned 1.0.0). At least one difference is that the magic_descriptor function in the former restores the position in the file whose fd has been passed, while the latter seems to be based on the https://github.com/aidansteele/MagicKit/tree/master/libmagic version of libmagic, which closes the file descriptor (see e.g. the close_and_restore function in magic.c).
I believe that the "file" version makes much more sense, as using magic_descriptor implies that the programmer passes the fd of an opened file, and has no reasons to expect that this function will close this fd. 
Is it possible to change to this one ?
