Prior to a fix in CMake 3.1:

 CMakeConfigurableFile: Remove excess newline.
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=e2f09aff

it actually had *two* trailing newlines.

Currently CMakeConfigurableFile.in is not documented at all.  One could
document it and add a version without a newline.  However, see below.

Is there any reason not to use file(GENERATE) instead?
