From 7a5d434e34519335107187f26bbd7674a0a31334 Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Thu, 25 Feb 2016 20:39:22 +0000 Subject: [PATCH] Make some static text in GTK dialogs selectable. I've made the licence text, the About box, and the host key dialog into GTK selectable edit controls. (The former because it contains a lot of text; the About box because pasting version numbers into bug reports is obviously useful; the host key because of the fingerprint.)
