Eh, no, look again.  What it's actually doing is reading $inputdir/input/
and converting into $outputdir/sql/, and reading $inputdir/output/ and
converting into $outputdir/expected/.  I guess that works, but again it's
kind of at variance with the normal expectation of VPATH behavior.  What
you'd expect is that $builddir/input files would override $srcdir/input
files; but as is, $builddir/input and $builddir/output are never examined
at all.
