compression: introduce an official `zstd-revlog` requirement...
compression: introduce an official `zstd-revlog` requirement This requirement supersedes `exp-compression-zstd`. However, we keep support for the old requirement. Strictly speaking, we do not need to add a new requirement, there are no logic change making "new" repo incompatible with mercurial client using a version that support `exp-compression-zstd`. The choice to introduce a new requirement is motivated by the following: * The previous requirement was explicitly "experimental". Using it by default could confuse users. * adding support for a hypothetical third compression engine will requires new code, and will comes with its own requirement tool. * We won't use it as the default for a while since I do not think we support zstd on all platform. I can imagine we'll gain another (unrelated but on my default) requirement by the time we turn this zstd by default.

"""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.
