In your tree, yes.

And when I export the patch, we get the proper:
	create mode 100755 scripts/pahole-flags.sh
line added to the patch.

But then when importing the patch using:
	git quilt-import
that line is totally ignored and the permissions are set to normal.

It's a long-running issue, and I think I'm about the only one that uses
git quilt-import outside of the debian build system, so it's low on my
list of things to fix up with that shell script (speed is my biggest
issue, it's just slow on large amounts of patches and needs to be
rewritten in C).

I'll go fix this up by hand...
