Previously the heuristic check for links required spaces before the
attribute to ensure that attributes suffixed with `id` were not
identified. This has now been expanded to any white space character to
enable the `id` attribute to start on a new line.
Currently the Configuration docs says to load syntax files into
config.toml [markdown] extra_syntaxes. However, ever since commit
23064f57c8 (released in Zola v0.15.0), the extra_syntaxes property was
replaced by extra_syntaxes_and_themes, and used as both syntax and color
theme search paths. Following the docs and trying to set the
extra_syntaxes property does nothing, and #1723 ran into this issue.
Change the docs to consistently reference extra_syntaxes_and_themes.
The [RFC](http://www.robotstxt.org/orig.html) mentions only `Disallow`
directive, so it must appear in the file.
`Allow` is an ad hoc agreement between search engines that no all of
them follow.
* Correct Windows paths
\\ is only for the beginning of UNC paths, e.g.
\\host-name\share-name\file-path
as per
https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file
* Remove spaces path list using brace expansion
In the shell, spaces are significant in a path with brace expansion, and
break it. (As opposed to in Rust module brace expansion.)
* add external_level and internal_level
* remove unnecessary debug derive on LinkDef
