This sounds reasonable, but I don't think it is.  :-)
`browse-url-default-browser' is just a symbol that that variable had as
a value.  Yes, it's a symbol that refers to a function, but in general,
the doc machinery doesn't know that that's how it's going to be used; it
might be a total coincidence.  (Especially with shorter symbols.)

So I'm closing this bug report.
