> Subject: [PATCH] doc: fix build on Windows with meson 0.58
> 
> The `doc` target used `echo` as its command.
> On Windows, `echo` is always a shell built-in, there is no binary.
> Starting from meson 0.58, `run_target()` always searches for command
> executable and no longer accepts `echo` as such on Windows.
> Replace plain `echo` with a Python one-liner.
> 
> Fixes: d02a2dab2dfb ("doc: support building HTML guides with meson")
