* Command line completion code was inadvertently made incompatible with
older versions of bash by using a newer array notation.
+ * Scripts to test bash completion was inherently flaky as it was
+ affected by whatever random things the user may have on $PATH.
+
+ * A fix was added to the build procedure to work around buggy
+ versions of ccache broke the auto-generation of dependencies, which
+ unfortunately is still relevant because some people use ancient
+ distros.
+
* We used to stuff "user@" and then append what we read from
/etc/mailname to come up with a default e-mail ident, but a bug
lost the "user@" part.
* Attempt to "branch --edit-description" an existing branch, while
being on a detached HEAD, errored out.
+ * "git cherry-pick" did not replay a root commit to an unborn branch.
+
+ * We forgot to close the file descriptor reading from "gpg" output,
+ killing "git log --show-signature" on a long history.
+
* "git rebase --preserve-merges" lost empty merges in recent versions
of Git.
+ * Rebasing the history of superproject with change in the submodule
+ has been broken since v1.7.12.
+
+ * A failure to push due to non-ff while on an unborn branch
+ dereferenced a NULL pointer when showing an error message.
