evaluate appears not to catch all output?

[MichelNivard]

when I run:

evaluate::evaluate("?hist()")

or

evaluate::evaluate("help(hist)")

the contents of the help page aren't caught and cant be replayed? is this a bug or expected behaviour?

Technically help files are not printed; they're opened in a separate viewer process. If you want to control this you could override utils:::print.help_files_with_topic with your own implementation.
