This seems to work fine for me. If I do:

  {
	echo "Version 0.0.0"
	echo
	echo "An example."
	echo
	echo "Insertions: 10"
  } >input
  git tag -F input foo

then your example above produces:

  foo  2024-09-06  Jeff King  Version 0.0.0  Insertions: 10

I wonder if the contents of the tag are not exactly as you expect, and that is fooling the trailer parser (which relies on some heuristics to find the right spot). Can you show us the output of "git cat-file tag <some-tag>"? Mine looks like:

  $ git cat-file tag foo
  object af1c73c21ab34cfbdc86da838acacc6e45ccd264
  type commit
  tag foo
  tagger Jeff King <peff@peff.net> 1725595316 -0400
  
  Version 0.0.0
  
  An example.
  
  Insertions: 10
