+Subject: [PATCH] build: Avoid the doctemplates hack
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The hack that copies the doctemplates directory into the build
+directory has stopped working with newer versions of Meson; while it's
+possible to copy files, custom_target() cannot depend on a directory.
+Additionally, the dependency has always been broken.
+
+Instead, we enumerate the template files—after all, it's not like they
+change a lot—and then we list them as dependencies for the test targets.
+
+Fixes: #414
