Here's one study about the benefits of using indentation, "(Program
indentation and Comprehensibility, Richard Miara, et al, CACM Volume
26
Issue 11 (November 1983)":
http://portal.acm.org/citation.cfm?id=358437&dl=ACM&coll=portal (see
the
PDF link near the top).

A quote from the conclusion:

"In summary, we conclude that some indentation does aid program
comprehension. From our results, we suggest that the optimal level of
indentation is 2-4 spaces. No indentation produced significantly lower
mean scores and the subjects found working with this program
difficult.
We conclude that in a large program, no indentation would be a real
hindrance and very difficult to use. The same is true for overly
indented programs."
