I have just had something similar happen. An extra ^M was inserted at
the start of a line well down the ChangeLog file somewhere in the process.

In my case, Emacs prompted me to revert ChangeLog after a CVS update and
before adding my ChangeLog entry.

Everything looked fine until I next reopened ChangeLog, where the line
end inconsistency caused the ^Ms to show up. The problem could have
happened at any of these points, but I suspect the second, as that is
the only one that is not part of my normal everyday use of CVS:

1. cvs update (file was unmodified locally at that time)
2. revert-buffer
3. add-change-log-entry
4. vc-next-action from vc-dired window with modified ChangeLog and one
other file marked.
5. cvs commit (resulting from step 4).

Because the ^M is treated specially by CVS, I'm unable to check in a
corrected version without making some other change to the file.
