The "immediate wreck" code

[Lincoln Peters]

I noticed that in the CVS Xconq sources, if a unit is set up to
immediately wreck in certain terrain, the help screen will report
"Immediate wreck in: false for all terrain types."  Even so, I find that
in "voyages" or "magellan", I can still run a fleet aground and wreck it
into a fort.

It's probably just a bug in the code for the "Help" screen, but it would
be quite annoying to anyone who doesn't read the GDL code instead of the
"Help" screen.
