pr on branch FSFormatting for #279

This pr fixes the identation issue as reported here https://github.com/fsharp/FAKE/pull/279#issuecomment-31400160. 

Again, only tested locally, as I do not have direct access to https://github.com/fsharp/FAKE/pull/279#issuecomment-31398875. (I opened my own account on TeamCity in order to be able to test my changes indepedently - pending.)

FakeLib needs to be rebuilt because of subsequent changes https://github.com/fbmnds/FAKE/commit/d1f530e527001b8f24388e131567fcc73f7e3076 / https://github.com/fbmnds/FAKE/commit/9544d943a03f97b991a59a3907c1f479ee9c6109 by @forki.
