How make patch in PHPStorm suitable for Drupal.org?

Question

PHPStorm will create patch in this form:

Index: core/modules/node/templates/node-edit-form.html.twig
IDEA additional info:
Subsystem: com.intellij.openapi.diff.impl.patch.CharsetEP
<+>UTF-8
===================================================================
--- core/modules/node/templates/node-edit-form.html.twig    (revision 4652b443e9f89734487e225fb76829595b5239a1)
+++ core/modules/node/templates/node-edit-form.html.twig    (revision )
@@ -1,6 +1,8 @@
 {#
 /**
  * @file
+ * Default theme implementation for a node edit form.
+ *
  * Two column template for the node add/edit form.
  *
  * This template will be used when a node edit form specifies 'node_edit_form'

After I export it I always have to remove the header and add the a/.. and b/.. prefixes and convert to LF so it'll look like this:

--- a/core/modules/node/templates/node-edit-form.html.twig
+++ b/core/modules/node/templates/node-edit-form.html.twig

Is there a way to export patch that I can directly use for drupal.org?

PHPStorm patching issues have a long history. I have corresponded with their staff more than once, about a year ago. They told me then, that my issue was taken up to developers, but never actually corrected it. Right now, PHPStorm issues patches incompatible with Drupal.org, and we can do nothing about it.

To create a working legit patch, you need git, and create a patch like this:

git diff > patch_name.patch

See http://drupal.org/node/707484
