Ahhh, it seems that the OP is using a too-old version of git.  I saw at
the bottom of the patch 2.39.5.  But the fix was part of 2.41.0.

	$ git describe --contains ab89575387c02ea024163256826ad1c6dd2e4247
	v2.41.0-rc0~141^2

This seems reasonable.  наб, would you mind not using that flag unless
you use a recent-enough git(1) (I suspect you're on an old Debian)?  :)

Have a lovely night!
