# Feature or enhancement

XML is maddening from a Git perspective, as if multiple tools will edit it, you'll get lots of lines in the diff that aren't needed.

For example:

```diff xml
diff --git a/sources/designspace/Besley.designspace b/sources/designspace/Besley.designspace
index d247944..eecb985 100644
--- a/sources/designspace/Besley.designspace
+++ b/sources/designspace/Besley.designspace
@@ -1,4 +1,4 @@
-<?xml version="1.0" encoding="UTF-8"?>
+<?xml version='1.0' encoding='UTF-8'?>
```

And:

```diff xml
diff --git a/sources/designspace/Besley.designspace b/sources/designspace/Besley.designspace
index d247944..9d570dd 100644

```

There are likely other issues, but I only needed to solve these two.
