obsolete: properly increment currentlen when building pushkey payload In the old code, the current length was always 0 leading to markers payload never being split.

hgweb: fixes invalid parents / children in comparison Previously, the parents / children were computed relative to the cset of the currently shown file, which was wrong and inconsistent with diff and others. With this patch, the listed csets are those that contain changes to the currently compared file, which don't necessarily have to be the direct parents and children of the changeset itself.

hgweb: fixes traceback for invalid files by removing top-level template The top-level 'comparison' template was not really needed, and it also caused a traceback to be shown for inexistent files (as reported by Ross Lagerwall). Getting rid of it makes the overall templating structure simpler and causes invalid files to be handled nicely.
