Thanks. I was going to produce something this morning, but you have
been faster than me.

One thing that's changing in this patch is that testtablespace would
be created even if the input directory does not exist when using
--make-testtablespace-dir. I would have kept the creation of the
tablespace path within convert_sourcefiles_in() for this reason.
Worth noting that snprintf() is used twice instead of once to build
the tablespace path string. The Windows part works correctly.
