dirstate-v2: Change the on-disk format when the requirement is enabled
For now, the format is the same except with an additional marker at the start.
This marker is redundant: for existing repositories it is `.hg/requires` that
determines which format to use. For new repositories, it is the new
`format.exp-dirstate-v2` config. There is no upgrade or downgrade so far.
Most of the changes are about plumbing a boolean through layers of APIs to
indicate which format should be used.

# 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.
