* "git checkout $tree" did not trigger an error.
+* "git commit" tried to remove COMMIT_EDITMSG from the work tree by mistake.
+
* "git describe --all" complained when a commit is described with a tag,
which was nonsense.
+* "git fsck branch" did not work as advertised; instead it behaved the same
+ way as "git fsck".
+
* "git log --pretty=format:%s" did not handle a multi-line subject the
same way as built-in log listers (i.e. shortlog, --pretty=oneline, etc.)
