Bug#902369: diffoscope: too many warnings when acl not installed

[Reiner Herrmann]

Package: diffoscope
Version: 96
Severity: minor

Hi,

I just wanted to compare two directories for differences, when
diffoscope "spammed" my terminal with warnings that it can't find
'getfacl':

2018-06-25 15:05:08 W: diffoscope.comparators.directory: Unable to find 'getfacl', some directory metadata differences might not be noticed.
2018-06-25 15:05:08 W: diffoscope.comparators.directory: Unable to find 'getfacl', some directory metadata differences might not be noticed.
2018-06-25 15:05:08 W: diffoscope.comparators.directory: Unable to find 'getfacl', some directory metadata differences might not be noticed.
[...]
2018-06-25 15:05:08 W: diffoscope.comparators.directory: Unable to find 'getfacl', some directory metadata differences might not be noticed.

Indeed I don't have the acl package installed which provides getfacl.
But I think a single warning should be sufficient. I don't need one for
every file inside the compared directories. :)

Kind regards,
   Reiner
