From 1e752ae33791652d050e7d03e6d8e9df3fb459e3 Mon Sep 17 00:00:00 2001
From: Santtu Lakkala <inz@inz.fi>
Date: Thu, 17 Feb 2022 18:11:35 +0200
Subject: [PATCH] Open url from clipboard
Based on the previous versions of the patch, but uses double-fork/execlp
instead of system() to avoid potential shell escaping issues and make
the command line building unnecessary.
