How to see Macports patches

[Jeffrey Walton]

Hi Everyone,

I want to see the patches applied to Unistring
(https://www.gnu.org/software/libunistring/). I found the package in
search at https://www.macports.org/ports.php?by=name&substr=libunistring
. Following the "source" link to Macport's GitHub I see
https://github.com/macports/macports-ports/blob/master/textproc/libunistring/Portfile
, but it does not have the patches.

Where can I find the patches for Unistring?
