    evolve: use functions from topic extension to set current topic and tns · ddebaa161306
    Anton Shestakov authored
    In some cases in evolve we need to relocate commits on disk instead of purely
    in-memory. Previously we were writing .hg/topic file by hand here, but it
    wasn't the right thing to do, and also we could sometimes write an empty string
    to the file. Let's use the functions in topic that are specifically made to
    change current topic and tns.
    
    I don't think we can simply manipulate commit extras to copy topic and
    topic_namespace, because sometimes we can have unresolved merge conflicts
    (since we're dealing with relocating on disk), and in this case users might
    need to continue evolve later after resolving the situation, so I think we
    definitely want to write current topic and tns to the files for persistence.
