Josh wants to change the default behaviour.  Better be prepared
not to be affected by it.

-+GIT v1.5.2 Release Notes
-+========================
-+
-+Updates since v1.5.1
-+--------------------
-+
-+* New commands and options.
-+
-+* Updated behavior of existing commands.
-+
-+  - "git diff --stat" shows size of preimage and postimage blobs
-+    for binary contents.  Earlier it only said "Bin".
-+
-+  - "git lost-found" shows stuff that are unreachable except
-+    from reflogs.
-+
-+* Builds
-+
-+  - git-p4import has never been installed; now there is an
-+    installation option to do so.
-+
-+  - gitk and git-gui can be configured out.
-+
-+  - Generated documentation pages automatically get version
-+    information from GIT_VERSION
-+
-+* Performance Tweaks
-+
-+  - optimized "git-rev-list --bisect" (hence "git-bisect").
-+
-+  - optimized "git-add $path" in a large directory, most of
-+    whose contents are ignored.
-+
-+
-+Fixes since v1.5.1
-+------------------
-+
-+These are all in v1.5.1.x series.
-+
-+* Documentation updates
-+
-+* Bugfixes
