treemanifest: allow manifestrevlog to take an explicit treemanifest arg
Previously we relied on the opener options to tell the revlog to be a tree
manifest. This makes it complicated for extensions to create treemanifests and
normal manifests at the same time. Let's add a construtor argument to create a
treemanifest revlog as well.
I considered removing the options['treemanifest'] logic from manifestrevlog
entirely, but doing so shifts the responsibility to the caller which ends up
requiring changes in localrepo, bundlerepo, and unionrepo. I figured having the
dual mechanism was better than polluting other parts of the code base with
treemanifest knowledge.

# highlight - syntax highlighting in hgweb, based on Pygments # # Copyright 2008, 2009 Patrick Mezard <pmezard@gmail.com> and others # # This software may be used and distributed according to the terms of the # GNU General Public License version 2 or any later version. # # The original module was split in an interface and an implementation # file to defer pygments loading and speedup extension setup. """syntax highlighting for hgweb (requires Pygments) It depends on the Pygments syntax highlighting library: http://pygments.org/ There are the following configuration options:: [web] pygments_style = <style> (default: colorful) highlightfiles = <fileset> (default: size('<5M')) highlightonlymatchfilename = <bool> (default False) ``highlightonlymatchfilename`` will only highlight files if their type could be identified by their filename. When this is not enabled (the default), Pygments will try very hard to identify the file type from content and any match (even matches with a low confidence score) will be used.
