topic: don't take topic into account when pushing to non-topic repo
Previously, pushing to a non-publishing repository without topic support would
wrongfully use topic when searching for new heads.
# topics
Topics are an experiment to see if maybe the workflow defined by git
branches and hg bookmarks is only partially what users want - perhaps
something that feels more like a traditional VCS branch is right, but
that it should "dissolve" upon being finished. This extension exists
to be a sandbox for that experimentation.
# usage
Enable topics like any mercurial extension: download the source code to a
local directory, and add that directory to your `.hgrc`:
[extensions]
topics=path/to/hg-topics/src
If you are using Mercurial 3.7 use:
[extensions]
hgext3rd.topics=path/to/hg-topics/src
