Hello,

The attached patch changes the indentation of IF forms from (if foo bar baz) to (if foo bar baz) which is, AFAIK, the most widespread way of indenting IF forms.

Also, this patch http://common-lisp.net/~loliveira/patches/slime-changelog-nuke-trailing-whitespace.diff removes lots of trailing whitespace from the ChangeLog via M-x delete-trailing-whitespace.
