[plt-scheme] parser funky

Something funky is going on with the parser in the latest svn (version
4.2.1.4-svn28jul2009).

In Beginning Student, I enter the following program and with the
cursor after the last paren of the function, nothing is highlight,
after the second-to-last, it highlights that paren in pink, suggesting
that it's unbalanced.

Also, auto-indenting seems to be confused when I hit enter after the
first close paren.

Is it just me?
