allow customization of '@family' prefix

[kevinushey]

When using e.g.

#' @family foo

The documentation gets an entry in the seealso section as:

Other foo: <...>

I'd like to be able to customize the prefix, so that I could just write e.g.

#' @family Environment management

and just have a plain old:

Environment management: <...>

ie, without the Other: prefix. Does that seem sensible?

tl;dr: "Other:" isn't always a great prefix and I'd like to customize that somehow.

More generally, it would be 'nice' to be able to map family names (e.g. 'foo') to a particular prefix / label for when that set of functions are rendered.

I think this is a reasonable request, but I just don't see where you'd define the lookup. If you can think of a reasonable place to store that data, I'd consider implementing it.

How would you feel about a subfolder like meta-roxygen that encoded this in some way? E.g. we could have meta-roxygen/family.json and we could map family names to prefixes there. (or it could just be an .R file, or some other appropriate representation)

[hadley]

I wonder if we could put that in man/ or man/roxygen?

[kevinushey]

I like man-roxygen. I'll prototype something.
