Thanks for the suggestion.
I've done this:

        * coreutils.texi (nl invocation): Specify that these are _basic_
        regular expressions (BRE), and add a link to grep's documentation.
        Suggestion from Dan Jacobson.

I'm deferring the corresponding change to nl's --help output
until after coreutils-5.2.1.
