Patch to udev.7 to clarify $attr{} parent searching

["Karl O. Pinc" <kop@meme.com>]

[-- Attachment #1: Type: text/plain, Size: 449 bytes --]

Attached patch against udev.7 of udev-124.

Clarifies that the first match is used when
$attr{} substitution searches through parent
devices.

Apply in udev-124 directory with:
patch < /foo/udev.7-patch

(Also, I didn't make the change, but shouldn't
the last sentence of the patched paragraph be
a new paragraph?)
