Everyone please rest assured that I'm well ware of this all, otherwise I
wouldn't have gone through all the flying optimization circus for 21.

P.S.

Too bad that the commit history of all that stufff was lost when I
integrated it into the RCS "repo" on gnu.org, which was just a shared
directory.  The commits would have been a nice proof what a major PITA
the optimization were, for years.  That, and making stuff
backward-compatible.  The ChangeLogs told only a fraction of the story
because I edited them and gave them all the date of integration.  Which
looked reasonable at the time :-).
