In gh-145455, an outdated dependency caused an import error that was not printed out (2>&1); the message instead said that the tools are missing.

Don't redirect stderr, to show warnings and failures.

Also, switch blurb to output a version on a single line (--version rather than help), and, and don't redirect stdout either. This results in two version info lines being printed out. These get drowned in typical Sphinx output, and can be helpful when debugging.

In pythongh-145455, an outdated dependency caused an import error that was not printed out (`2>&1`); the message instead said that the tools are missing. Switch `blurb` to output a version on a single line (`--version` rather than `help`), and don't redirect stderr, to show warnings and failures. Also, don't redirect stdout. This results in two extra lines with version info, which get drowned in typical Sphinx output, and can be helpful when debugging.

Thanks!

I think this is worth backporting to security branches as well.

This first came up in a security branch, and it's more likely for their old dependencies to break, and this fix will help debug.

Yeah.
But I'd like to wait for slow CI before asking the bot to make backports there.
