Yes, in this case the Author info is replace with the same exact info.
But I was thinking generally. I.e., most non-maintainer contributions
would also be a group of files. Ethan would have the most insight on
how this is characterized. The problem is that contributions which only
change a single file could, with higher probability, be on a day when
someone else made a modification to the same file.
BUT, I may have hit upon a more reliable and straightforward approach
from an automated script standpoint. It's based on what I pointed out
about the ChangeLog file typically being listed in the diff hunks.
Experiment with the following git command:
git log -p --unified=20 ChangeLog
That gives us the log record for the ChangeLog, printing out the diff
hunks in the ChangeLog and with enough context lines such that it
displays back to the Date/Contributor/Address line. (Use --unified=30
if one thinks there could be that length of comment.)
With such a record, the script can search for the changes in the file
(i.e., "+" as character in the first location of the line), and then
search backward for the Date/Contributor/Address info. With a few
heuristic rules, this might be rather accurate, in theory. Let's look
at some examples.
Here's one that's pretty simple, the Author info is the first modified line:

Attempt to handle the case of linked axes (x+x2 or y+y2) and an in-line

Recommend to use separate "set xrange ... set yrange ..." instead.

How about the scenario of my previous post where the commits are a

* src/win/wd2d.cpp: Enable color font support. This enables colored
emojis, which can be used e.g. as point symbols. Due to the default
font-fallback to "Segoe UI Emoji", this might lead to unexpected
results if a plot relied on non-colored character fallbacks.

wgnuplot. Note that the process terminates if the new console is
closed, just as is the case with wgnuplot_pipes, but the console is
only opened when actually required.
-------------------------
Notice in the above how having enough context lines shows us the Author
information (searching backward from the first changed line in the
ChangeLog file) even though Bastian appended to the end of the previous
ChangeLog entry.
Does that approach seem fairly reliable and easy to automate?

That's good. To me, this seemed like the most "surgical" work.
