obslog: don't overwrite {rev} keyword from changeset context Now that we have the whole changeset in the formatter context, there's no need to explicitly add {rev}. We should also deprecate the {shortdescription} keyword since it's no longer needed, but I don't know how to do that.

obslog: make changeset available to templater obslog templating currently has very limited support for templating the precursor changeset (when available). The only available keywords are {node}, {rev}, and {shortdescription}. This patch makes the entire changeset available to the templater by passing it to formatter.context(). That function has been available since Mercurial 4.2.
