Re: Apropos commands and regexps

[Richard Stallman]

    The way I envisioned it was all apropos commands taking _list_ of
    regexps (separated by whitespace/commas), and applying them in an `and'
    manner.

The other suggestion, to look for names that contain at least two of the
specified terms, seems more useful to me.

    Given the particular nature of apropos usage in emacs, I think there
    wouldn't be any conflict in practice from using whitespace/commas as
    the list delimiters.

I agree.

    There might also be other things we can do, like if a term begins with
    an alphabetic character, anchor it with \<.

I disagree; I think it is better to allow prefixes too.
That will tend to find a small number of extra matches,
which will not do much harm, and sometimes it will do good.
