Greetings, Michael Goldshteyn!

Oh, so THAT's what causing my git diff to disappear!

>> [C:\]$ set cyg
>> CYGWIN=wincmdln winsymlinks:native glob:ignorecase
>> CYGWIN_DIR=C:\Programs\Cygwin
>> CYGWIN_MIRROR=https://ftp-stud.hs-esslingen.de/pub/Mirrors/sources.redhat.com/cygwin

>> [C:\]$ mintty -- git diff --minimal "--diff-filter=MAD" --find-renames=70 --irreversible-delete HEAD --

>> # The actual executed command is:

I don't think that's how it is supposed to work.
