It seems that http://commitfest.cputube.org/ runs only "make check" on
Windows.  But my Postgres Pro colleagues checked that tests passed on
32-bit and 64-bit versions of Windows Server 2008.  Also I made some
minor beautifications on code and documentation.

This patch seems to have good shape and generally being quite
harmless.  Do we have any objections to committing this?
