The unusual syntax --rebase-merges="" (that is, --rebase-merges with an empty string argument) has been an undocumented synonym of --rebase-merges without an argument. Deprecate that syntax to avoid confusion when a rebase.rebaseMerges config option is introduced, where rebase.rebaseMerges="" will be equivalent to --no-rebase-merges. It is not likely that anyone is actually using this syntax, but just in case, deprecate the empty string argument instead of dropping support for it immediately.
