Subject: diffoscope: wrongly reports "No differences found inside, yet data 
differs"
Package: diffoscope
Version: 51
Severity: normal

Dear Maintainer,

when comparing two initramfs images [1,2], diffoscope reports:

[2] http://in.waw.pl/~zbyszek/diffoscope/initrd

   [ Juliana Oliveira Rodrigues ]
   * comparators:
     + utils:
       - compare: fix comparison between container types.
       - container: add get_path_name() method, aiming at preventing hitting
         OS' max filename length.
     + gzip: replace dest_path generation with self.get_path_name().
     + bzip2: replace dest_path generation with self.get_path_name().
   * tests:
     + presenters:
       - skip html_visuals test if 'sng' binary is not available.
     + comparators:
       - test_cointainers: new tests to test cross-container comparisons.
       - add test_containers.py.
 .
   [ Chris Lamb ]
   * comparators:
     + utils:
       - file: correct reference to path_apparent_size.
     + fonts: loosen matching of file(1)'s output to ensure we correctly also
       match TTF files under file 5.32.
     + binwalk:
       - new comparator to deal with (e.g.) concatenated CPIO archives using
         the new optional python module 'binwalk'.  Closes: #820631
   * diffoscope.diff: Correct reference to self.buf.
   * debian/rules: run flake8 during the tests, and fail the build in case the
     "underfined name" flake8's check fails.
   * tests/comparators:
     + test_cpio: check we identify all CPIO fixtures.
   * main:
     + print a debugging message if we are reading diff from stdin.
   * presenters:
     + html: use logging.py's lazy argument interpolation.
   * debian/control: bump Standards-Version to 4.1.0.
   * Code style improvements across all of the codebase.
 .
   [ Mattia Rizzolo ]
   * debian/changelog: retroactively close a bug in an old changelog entry.
   * setup.py: add a check to prevent people from installing diffoscope under
     python < 3.5 (i.e. python2) and give them a usable error message otherwise.
   * Code style improvements across all of the codebase.
 .
   [ Ximin Luo ]
   * comparators:
     +  add a fallback_recognizes() method to work around file(1)'s bug #876316.
        Closes: #875282
     + add a --force-details flag for debugging.
     + deb:
       - if --force-details then don't skip files with identical md5sums either.
   * presenters:
     + html:
       - prune all descendants properly.  Closes: #875281
       - don't show pointer-cursor when jquery is disabled.
   * config:
     + force-set a value if it must be less than another, and it was not set on
       purpose.  Closes: #875451
   * readers: convert bytes to str in the right place.
   * diff: use diff_split_lines everywhere.
   * difference:
     + in fmap/map_lines, don't forget about self._visuals.
     + also copy self._comment properly, compare self._visuals in equals().
   * tests/comparators:
     + test_deb: make test_md5sums less brittle.
