Perhaps we should set 'blame.ignoreRevsFile'[1] in the Emacs repo's Git 
config (and then add this commit SHA to that file)? That should make 
vc-annotate - and anything else that uses "git blame" - ignore this 
commit, along with any other mechanical commits that shouldn't count for 
the purposes of blame.

I believe this was introduced in Git 2.23 (from Aug 2019), so most 
people with relatively-recent Git installs should be able to use this. 
I'm not sure how robust this feature is (i.e. can it properly ignore 
complex changes?), but for changing tabs to spaces, that should be 
pretty trivial for Git to figure out.
