+@code{fill-region}.
+
+The chief improvement is that the beginning of a line to be
+filled is examined and, based on information gathered, an
+appropriate value for fill-prefix is constructed.  Also the
+boundaries of the current paragraph are located.  This occurs
+only if the fill prefix is not already non-nil.
+
+The net result of this is that blurbs of text that are offset
+from left margin by asterisks, dashes, and/or spaces, numbered
+examples, included text from USENET news articles, etc. are

+
+This adds an environment variable MINETEST_MOD_PATH.
+When it exists, Minetest will look there for mods
+in addition to ~/.minetest/mods/.  Mods can still be
+installed to ~/.minetest/mods/ with the built-in installer.

+With thanks to Leo Prikler.

+Subject: [PATCH] rsync_remote: Fix a problem when receiving read-only
+ directories.
+
+Before this change, when the source directories hierarchy was
+read-only, the read-only mode would be preserved at the destination,
+preventing child directories to be recreated by a normal user (a
+permission denied error, EACCES would be raised).
+
+* execnet/rsync_remote.py (serve_rsync.receive_directory_structure):
+Bitwise OR to ensure the write bit is set on received directories.
+* testing/test_rsync.py (TestRSync)
+<test_read_only_directories>: New test.
