AnaGram interim repo (temporary): doc/misc/html/examples/ffcex.html annotate

annotate doc/misc/html/examples/ffcex.html @ 21:1c9dac05d040

Add lint-style FALLTHROUGH annotations to fallthrough cases. (in the parse engine and thus the output code) Document this, because the old output causes warnings with gcc10.
