indentation of backquoted forms

[David Chapman <Zvona@MIT-OZ>]

In zwei in Release 4.1, System 222.186, Hardcopy 11.14, Zmail 74.43,
LMFS 30.26, Knowledge-Based-Editor 164.19, site configuration 19,
Black Magic, on Lisp Machine Twenty-two:

Tab gives you the following indentation:

(,predicate-name (,(if lower? 'second 'third) (elist examples))
 diachronic-theory
 synchronic-theory
 relation
 examples)

I would have expected

(,predicate-name (,(if lower? 'second 'third) (elist examples))
                 diachronic-theory
		 synchronic-theory
		 relation
		 examples)
