In preparing the new patchset, I've put a big comment block explaining why we need to set both $hash and $hash_base in this code-path:

# we got "project.git/[action/]branch". in this case # we set both $hash and $hash_base because different actions # need one or the other to be set to behave correctly. # # For example, if $hash_base is not set then the blob and # history links on the page project.git/tree/somebranch will # assume a $hash_base of HEAD instead of the correct # somebranch. # Conversely, not setting $hash will make URLs such as # project.git/shortlog/somebranch display the wrong page. # # Since it also turns out that the unused one is properly # overwritten as needed, setting both is quite safe.
