ubuntu.yml, macos.yml and windows.yml run about 155 jobs on every pull
request, including those that change only the documentation. They now
have a pull_request path filter: it starts with '**' and excludes the
documentation, Markdown files, GitHub metadata, other workflows and the
license files, so a new file runs them unless it is excluded on purpose.
Pushes to develop, master and release/* are not filtered.
The documentation jobs and the REUSE check move from ubuntu.yml to the
new repository_checks.yml, which has no path filter and also runs
tools/check_path_filters. That check keeps the three filters identical
and fails when a file the compiler jobs keep mentions an excluded file.
It found two: tools/check_build_options reads the Meson section of
package_managers.md, and the swiftpm job builds the Swift example from
the documentation; both are included in the filter.
