Possible incorrect expression precedences for DotReference, BracketReference and CallExpression

Hi Dave,

I think there's a pretty printing bug in versions 6 and 7 of javascript.plt. You gave DotReference? and CallExpression? a different precedence in version 6 (they were the same in version 5) and it causes some expressions to render in odd ways.

I've attached a new version of private/tests/pretty-print.ss containing extra tests that illustrate the problem (see lines 51 to 102).

I've also attached a version of print.ss with slightly altered precedences that make all the tests work (including all the test cases in Mirrors).

I think we're getting very close to library harmony now (pun intended).

Excellent! Thanks for the fix. It's applied in 7:4. (Nice pun.)
