I've enhanced my utility with the following subtle change:  search for 
first item (i.e., line has a star * or colon :) within the addition diff 
hunk.  This corrected 4 entries, which I've listed on SourceForge here:

https://sourceforge.net/p/gnuplot/patches/763/#5709

Here's an example of those 4 in which the first added line is a space 
and the author info appears in the second changed line, not the first:

@@ -1,50 +1,58 @@
+
+2000-09-20  Jjjjjj Zzzzzz <xxxxxx@xxxxxx>
+
+   * relative arrows:

So, the new algorithm will search until finding the * of "  * relative 
arrows:" (line 4).  Then searching backward from that point (line 4) 
will find the proper author (line 2).
