Git's default hunk pattern recognizer favors the C language, but it
also includes several built-in diff styles that give saner results in
other languages. In particular, telling git to treat all .py files as
python changes the beginning of diff hunks as follows:
| --- a/python/qemu/machine.py
| +++ b/python/qemu/machine.py
| -@@ -337,12 +337,12 @@ class QEMUMachine:
| +@@ -337,12 +337,12 @@ def _post_shutdown(self) -> None:
| self._qmp.close()
which makes it much easier to tell what function a patch is touching,
rather than a non-descript listing of what class contains the changes.
Sadly, our python files that don't use .py suffix (such as numerous
iotests) do not benefit from this glob.

Since commits 0979ed017f ("meson: rename .inc.h files to .h.inc")
and 139c1837db ("meson: rename included C source files to .c.inc")
'git-diff --function-context' stopped displaying C function context
correctly.
We can help git-diff by providing attributes to the .[ch].inc path
names. See:
