bundlerepo: bundle repos should be non-publishing (issue3266)
Bundle repo contains both the bundle content and the content of the repository
used as a base. This create bugs with phases exchange because the "remote"
repository claim to contains changeset it does not. The easiest way to fix this
bug is to ensure a bundle repo as non publishing. This way changeset will be
seen in the same phase than locally.
This patch does not alter in which phase bundle revision are seen. For now they
are seen as if an old client had add them on the remote: They inherit their
phase from parent whatever the parent is. This is to be fixed in a later patch

'''browse command output with an external pager To set the pager that should be used, set the application variable:: [pager] pager = less -FRSX If no pager is set, the pager extensions uses the environment variable $PAGER. If neither pager.pager, nor $PAGER is set, no pager is used. If you notice "BROKEN PIPE" error messages, you can disable them by setting:: [pager] quiet = True You can disable the pager for certain commands by adding them to the pager.ignore list:: [pager] ignore = version, help, update You can also enable the pager only for certain commands using pager.attend. Below is the default list of commands to be paged:: [pager] attend = annotate, cat, diff, export, glog, log, qdiff Setting pager.attend to an empty value will cause all commands to be paged. If pager.attend is present, pager.ignore will be ignored. To ignore global commands like :hg:`version` or :hg:`help`, you have to specify them in your user configuration file. The --pager=... option can also be used to control when the pager is used. Use a boolean value like yes, no, on, off, or use auto for normal behavior.
