The patch is correct. The code is tricky so I'm not surprised you wanted
another pair of eyes. The attached patch is a very minor tweak of your
patch that made it a bit easier for me to follow. I resisted the
temptation of cleaning up the surrounding code to make it more readable.
I like the idea of putting this into the emacs-25 branch. (Or your
patch; doesn't really matter.)

Subject: [PATCH] Consing "V" into process-environment should remove V
Problem reported by Noam Postavsky (Bug#23779).
* src/callproc.c (add_env): Consider new string "FOO=BAR" to match plain
"FOO" in the old proto-environment. This is a slight tweak of the fix
suggested by Eli Zaretskii in http://bugs.gnu.org/23779#14
