Thanks!  The command you showed is the one variation I didn't try.
Hmmm, I must be missing something.

% cd /usr/src
%  git diff stable/13..main lib/msun
fatal: ambiguous argument 'stable/13..main': unknown revision or path
not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
% git status
On branch main
Your branch is up to date with 'freebsd/main'
