we want.  We need a mechanism that notices and warns when a commit
makes a file, which used to end with a newline, end in an incomplete
line.

Thank you for the clarity. This would mean to compare the relevant files in the
current commit with its parent commit and report when the current commit removes
the new line at the end of file which was present in the parent commit.

But how about when a file is newly added and lacks the new line?

Yes, you should notice and flag any new incomplete line that did not
exist before that are added by the commit.
