[Rd] mboost_1.1-3 blackboost_fit (PR#13972)

[Uwe Ligges]

Please read the FAQs about submitting bug reports. Bugs in contributed 
packages must not go to the R-bugs repository but to the corresponding 
package maintainer, CCing in this case (I do not confirmed that it is a 
bug).

Best,
Uwe Ligges
