Hello, I have the found the strange behavior of "git log -L" command with python function. It is counting a blank line that sits after a function's last statement as part of that function. This happens only when the function is at the end of a file.

The way to reproduce that

git init repro && cd repro git config user.email t@t && git config user.name t

printf 'def foo():\n return 1\n\n' > bug.py git add bug.py && git commit -qm c1

printf 'def foo():\n return 1\n' > bug.py git add bug.py && git commit -qm c2

Then do

git log -L :'foo':bug.py

And you'll see

Author: t <t@t>
Date:   Fri Sep 18 18:21:10 2026 +0300

c2

diff --git a/bug.py b/bug.py
--- a/bug.py
+++ b/bug.py
@@ -1,2 +1,3 @@
 def foo():
     return 1
+

Though I expect that commit "c2" should never appear in log, since the changes from it doesn't affect the functions body at all.
