How can I get git diff to ignore changes like:
a + b + c
to
a +
b +
c
i.e, treat all sequences of whitespace as identical for the purposes of diff?
Note that given file1:
a + b + c
and file2:
a +
b +
c
running
git diff -w --word-diff-regex=[^[:space:]] file1 file2
gives:
diff --git a/file1 b/file2
index baaa7f9..1ded6d8 100644
--- a/file1
+++ b/file2
@@ -1 +1,3 @@
a +
b +
c
not an empty diff as expected. Although the hunk presented actually has no changes (as in no lines begin with + or -). Is there a way to remove hunks with no changes?
