Bug#679763: debsnap: bisect option/script

[Osamu Aoki]

Hi,

For source history, "gbp inport-dscs --debsnap" gives you access to real
"git bisect" access.  So no point reinvention it in debsnap itself.

(Yes, I am living in high bandwidth region.)
 
For binary package history checking, dependency etc. matters and most
likely needs your manual attention.  At least with the new --list option
printing out sorted list of versions, you can do bisect like action
manually whice checking dependencyetively recent versions. 

Do you still think we should add complexities into debsnap?
