This is a bit more complete. It removes the possibility of rflag being equal to 3, the behavior of which, AFAICT, isn't defind.

Any -R overrides any -r.

Multiple/extra instances of -r are ignored (-rr is the same as -r).

There is still an implicit -r with -x.

Thanks, Max; but file-scope (statically-allocated) variables are automatically initialized to zero; only automatically-allocated variables (stack storage) require explicit initialization; this change wouldn't alter behavior.

In screen.c:

This appears to add to rflag, which might not already be initialized, accounting for inconsistency.

Patch attached.
