Subject: [PATCH] Fail when the showcase search skips an example a page renders

Plan step 38 review: the index reads example titles out of each
section's source with a regex, which once skipped all six Progress
examples without a sound; the existing test only checked that indexed
anchors exist. A new test renders every section and canonical layout
page and requires the index's examples for it to equal the titled
examples the page draws, both ways, so a format the regex misses (or
an anchor it invents) fails by page.
