Bug#888401: diffoscope: report differences in filesystem extended attributes

[Paul Wise]

Package: diffoscope
Version: 90
Severity: wishlist

It would be nice if diffoscope could report differences in filesystem
xattrs. This would help when comparing directories with files that have
been downloaded with wget (or other downloaders that set xattrs).

In Debian we have two Python 3 modules for xattr support:

python3-xattr python3-pyxattr

~ $ mkdir 1 2
~ $ cd 1
~/1 $ wget -q https://www.debian.org/
~/1 $ cd ..
~ $ cp 1/index.html 2/
~ $ diffoscope --no-progress 1 2
