Multiple candidates is the most worrying for me as well. a-1.1 is masked and 
requires >=b-1.0. b has 1.0 and 1.1 both of which are masked. b-1.0 requires 
c-1.0 while b-1.1 requires c-1.1. c-1.1 masked but c-1.0 isn't. Should the 
above "keep going" just grab the highest *masked* version at each stage?

Either way, while there are bugs such as error messages being truncated, 
requests such as "allow me to break my system easier" are truly far from my 
mind. Of course, supplied patches will always be reviewed.
