True, understandable, and probably unavoidable. But probably most
users who are at the level of adding inline perl code aren't use the
cgi editor anyway.

Hopefully, the release notes will explain changes so that I can
correct things manually.
Also, I have been careful to keep my inline perl code to the
pc-specific config files in which I include only the small subset of
parameters that I need to vary by machine. So, presumably, the pain if
any at upgrade will be limited to those changes.
