transplant: add the transplanted revset predicate
This adds support to identify a particular transplanted changeset or set
of changesets. The argument is optional. Examples:
hg log -r 'transplanted(1234 or 2345)'
hg log -r 'transplanted()'
graphlog: style with header and footer (
issue2395)
The glog command didn't emit header and footer from the style, as demonstrated
by "hg glog --style xml". Asciiart combined with xml markup hardly makes sense,
but header and footer might however be useful for adding for example html pre
tags around the graph.

http nor gopher. daytime seems to be available everywhere.
