We're probably going to translate those that need massaging by hand,
as the automatic stuff we can do with regexp is just very simple stuff
anyway.
And Tcl8x leaks memory on regexps so we want to avoid doing them on
each and every query like we've done with OpenACS 3x/Tcl7x. ACS 4.1
uses Tcl8x language features and we've got to use it ...
