Dear maintainer.
I have been running into some issues lately regarding "python-magic". It appears that the Arch community package "python-magic" [1] which your Arch diffoscope package depends on, is not in fact the dependency that diffoscope expects, according to its own README [2] :

````
diffoscope requires Python 3 and the following modules available on PyPI:
libarchive-c [3],python-magic [4].
````

As you will see by looking at the PKGBUILD, the "python-magic" PyPi package is not what the "python-magic" Arch community package [1] provides, but a very different implementation of the "magic" library bindings for python. The AUR package "python-magic-git" [5] on the other hand does provide this "python-magic" PyPi package.

I realize this is probably of next to no importance, as the two implementations seem to at least be compatible enough to run this particular tool, but it is in the possible dependency/conflict interactions that there are consequences. For instance, in my case, I have utilities that specifically require the "python-magic" (github) implementation, and this conflicting with the "python-magic" (community) one makes it difficult for me to install diffoscope.

Would be very glad to get read your opinion and input on this.
Thanks for you time.
Regards,
Mark.
