Cancel this.  I just did some tests, and there amount of time required
for the validation (at least, in simple two-column table test) is < 10%
of the time required to reindex in general.  At that difference, we
don't need two options.

Unless you're asking if we want a command to check the index validity
without rebuilding it?  That might be more valuable ...
