That's not what I see.

ChangeLog.870 initially contains:

0000 7ff0 20 74 69 6d 65 2d 73 74  61 6d 70 2e 65 6c 3a 0d   time-stamp.el:.
0000 8000 0a 09 2a 20 74 69 6d 65  2e 65 6c 3a 0d 0a 09 2a  ..* time.el:...*

After rereading the file, in Emacs it shows as:

	* time-stamp.el:^M	* time.el:

which I interpret as if, while reading, the ^M was read without ^L and
so taken literally, while the ^L was missing.

Then, if I write it back, the file on disk contains

0000 7ff0 20 74 69 6d 65 2d 73 74  61 6d 70 2e 65 6c 3a 0d   time-stamp.el:.
0000 8000 09 2a 20 74 69 6d 65 2e  65 6c 3a 0d 0a 09 2a 20  .* time.el:...*

so a LF has gone missing.
