https://github.com/hexchat/hexchat/commit/15600f405f2d5bda6ccf0dd73957395716e0d4d3
Would be included in upstream source since the upload 2.12.3-0.1 to unstable but the
Debian packaging reverts the 15600f405f2d5bda6ccf0dd73957395716e0d4d3 commit
The Debian packagging drops the revert in 2.12.4-4 to not diverge from upstream.
