Why 3 line?  There are very long breakpoint scripts around.

Furthermore, when using breakpoint scripts to track some bugs (sometimes 
"condition" is not enough) it may be desirable to minimize the artifact.

If at least it would make the copy only when needed (i.e., when someone
is
trying to delete the breakpoint that has the script attached on it)
things
would not be that bad.
