The CR marker ^M doesn't show up in '-' lines of diffs when the ending

It shows up as expected in '-' lines when the ending of the removed line
is CR only.
It also always shows up as expected in '+' lines.
Is your repository configured to (1) highlight whitespace errors in
diff output and (2) to leave CRLF alone in text files?
I'm using the default configuration, so whitespace is set to
trailing-space, but cr-at-eol is not set.
If so, then it is just a side-effect of this combination, an illusion,
so to say: The CR in the CRLF combo is trailing whitespace. The 'git
diff' marks it by inserting an escape sequence to switch the color
before ^M and another escape sequence to reset to color after ^M. This
breaks the CRLF combination apart, so that the pager does not process
it as a combined CRLF sequence; it displays the lone CR as ^M.
Urghh... so that needs to be fixed.
Why does it work correctly with '+' lines ?
I don't think that there is anything to fix. If you have a file with
CRLF in it, but you did not declare to Git that CRLF is the expected
end-of-line indicator, then the CR *is* trailing whitespace (because the
line ends at LF), and 'git diff' highlights it.
