feat: allowlist

[pawelru]

Consider a package in a private repo that has the following DESC file:

Package: foo
Title: My private package
BugReports: 
    https://github.com/xyz/foo/issues

(there are more links in URL etc.)

Then urlchecker correctly identifies that the url is not accessible however this problem had been addressed by implementing proper repo access rights and from the package perspective I would like to treat that url as an exception and pass urlchecker.
I'm looking for something like WORDLIST file for spelling package.

urlchecker is the URL check code from base R, bundled up into a package, so I am reluctant to add new features to it, that would make the code different. But I'll think about it.

The other issue with a whitelist is that you'd get a clean check with urlchecker, but then if you submit the package to CRAN, it would fail the URL checks, because they do not have a whitelist.

In our case the problem is actually not in the package itself, but in the README.md file (which is listed in .Rbuildignore therefore not packaged). Would it make sense to exclude files that are covered by .Rbuildignore?

[gaborcsardi]

Maybe, but surprisingly it is very hard to decide which files are covered is in .Rbuildignore.

You could build the package into a proper source R package with R CMD build, and run urlchecker on that?
