[Rd] overriding built in Rbuildignore values

[Duncan Murdoch]

This is one reason why it's good to test devel, alpha and beta versions 
before release.

It's also a good idea to read the news items as they are added.  You can 
do that at pages linked from 
https://developer.r-project.org/RSSfeeds.html, or using an RSS reader.

In this case I don't think the news item would have signalled a problem, 
since it didn't list the new patterns:

"‘R CMD build <pkg>’ excludes more file patterns when it tars the <pkg> 
directory, fixing both PR#18432 and PR#18434, for ‘vim’ and ‘GNU Global’ 
‘emacs’ users, thanks to Dirk Eddelbuettel's patch. "

but often there's enough info there to at least encourage some tests.

I can do this once for the whole test suite, but then it means that I can't conveniently run individual tests during development. I have tens of separate tests using these files so running a setup/teardown for each individual test would require a significant amount of additional code tweaking.
