You may try https://git-scm.com/docs/diff-options#Documentation/diff-options.txt---word-diff-regexltregexgt

  printf 'if (xyz) biz()\n' > bar
  git commit -m 1 bar
  printf 'if (xyz)\n  biz()\n' > bar
  git commit -m 2 bar
  git diff --word-diff-regex='[^[:space:]]' HEAD~

yields a diff with differences hidden

diff --git a/bar b/bar
index 49d380e..05c8e60 100644
--- a/bar
+++ b/bar
@@ -1 +1,2 @@
if (xyz)
  biz()

But from gits perspective, the files are different and the lines are different.
This is the reason having an adhering to a formatting standard is advised,
and something IMHO every serious project should adhere to.
