-C is not really like -c. It really means "unbreak the default of !-c,
and preserve certain metadata". Preserving the metadata is the main
point of this option, but IIRC it was made as much like -c as possible
just as a first attempt to kill -c.

That was probably a mistake. Certainly merging it all back was. -C
is our (half my) flag, so we should know its intended use :-).

I'd like to get rid of it too. But not in RELENG_4. -c has been the default
for long enough now in -current. As you know, there are various problems
in using the correctly named variable for install(1)'s flags (INSTALLFLAGS)
to actually hold install's flags in a general way (mainly, this variable
already exists and is used in a non-general way). However, the old hack
of putting the flags in the same variable as the command still works well
except for the -[Cp] vs -d conflict. This depends on the flags not being
order-dependent.

I've complained to you before about this :-). Now I'm interested in getting
other ideas about it.
