Yes, I think I can take a stab at that.

My initial foray has raised one item of potential interest:

Git 2.22 Release Notes
======================
 * "git log -L<from>,<to>:<path>" with "-s" did not suppress the patch
   output as it should.  This has been corrected.
   (merge 05314efaea jk/line-log-with-patch later to maint).

I don't know whether there's any reason to support older git
versions, but I'm using git 2.17.1 and so the command generated
by `elpaa--get-release-revision' gives me this:

$ git log -n1 --no-patch --pretty=format:%H -L '/^;;* 
*\(Package-\)\?Version:/,+1:lisp/so-long.el'
b84986af52d4e9debace2850a5ec106f51e38e61
diff --git a/lisp/so-long.el b/lisp/so-long.el
--- a/lisp/so-long.el
+++ b/lisp/so-long.el
@@ -11,1 +11,1 @@
-;; Version: 1.1
+;; Version: 1.1.1

I didn't twig initially that I wasn't seeing the intended
output, and spent a while fruitlessly wondering where in the
elisp that got trimmed down to a single line...
