bundle: remove obsolete (and duplicate) comment Change 1e28ec9744bf (changegroup: move chunk extraction into a getchunks method of unbundle10, 2014-04-10) extracted some code to a getchunks() method and copied a comment about the changegroup format to the new method. The copy that remains in the old place, doesn't make much sense there, so let's remove it.

bundle: avoid crash when no good changegroup version found When using treemanifests, only changegroup3 bundles can be created. However, there is currently no way of requesting a changegroup3 bundle, so we run into an assertion in changegroup.getbundler() when trying to get a changroup2 bundler. Let's avoid the traceback and print a short error message instead.

exchange: make _pushb2ctx() look more like _getbundlechangegrouppart() The functions already have a lot in common, but were structured a little differently.

exchange: get rid of "getcgkwargs" variable This also makes the "version" argument explicit (never relies on getlocalchangegroupraw()'s default), which I think is a good thing.
