Thanks!

Huh, that's interesting! Here's the relevant code section from file's
src/fsmagic.c:
if (sb->st_mode & S_ISVTX)
if (file_printf(ms, "%ssticky", COMMA) == -1)
return -1;
sb is a stat(1) struct.
So, diffoscope uses regular expressions to match the output of file,
and many of the patterns use the start-of-string anchor (ie. "^").
We'll therefore need to find a way of convincing file to either not
prefix the string with "sticky" (and "setuid" or "setgid" now that I
look at the code...), or strip it out manually within diffoscope if
that is not possible.
(Seems a little odd that file adds this info at all IMHO. I would have
guessed that those are actually properties of the ~filesystem, not the
file itself...)
Anyway, should be easily fixed; will get to this ASAP.
Regards,
