The following patch will turn an unchanged Motsognir v1.0.11 source tree
into a Motsognir v1.0.11+logmore2.0 source tree.
Put this file into the source directory, chdir to the same directory,
then apply the patch with:
patch -p1 < motsognir1.0.11+logmore2.0.diff
You don't need to trim any text: the patch program knows what to skip.

+logmore2.0
+==========
+
+The logmore2.0 patch adds the following features to Motsognir v1.0.11:
+
++ New command line option '--log' allows users to specify either a log
+ file, or a syslog local facility number. This option is also available
+ as new configuration file directive 'log';
+
++ a directory specified on the command line is taken to be the
+ Gopher root;
+
++ standard options '--help', '--version'; plus '--license';
+
++ [NEW in 2.0] 'autoinfo' configuration directive: if set to 1, any
+ gophermap line containing no tabs is considered an "info line"
+ (no need for an initial 'i');
+
+* [NEW in 2.0] plus sign '+' characters in a URL are no longer
+ translated to spaces by the server; if you want the old behaviour
+ back, just remove '-DRFC3986' from the Makefile;
+
+! [NEW in 2.0] stricter validation on port number given in config file;
+
+* [NEW in 2.0] changes to the build/installation process:
+ * the Makefile now optimizes `motsognir' for size;
+ + new 'install-strip' recipe further reduces the binary's footprint;
+ * everything is installed under the '/usr/local' subtree, unless
+ otherwise directed (by setting DESTDIR and/or PREFIX);
+ ! an existing config file will not be overwritten upon installation;
+ + the paths referenced in the supplied init scripts and man page
+ are filled in at build time to make sure they match actual
+ installation paths;
+ * GNU Make is now required.
