* "git -c var=value subcmd" misparsed the custom configuration when
value contained an equal sign.
+ * "git fetch" had a major performance regression, wasting many
+ needless cycles in a repository where there is no submodules
+ present. This was especially bad, when there were many refs.
+
* "git reflog $refname" did not default to the "show" subcommand as
the documentation advertised the command to do.
