Allow passing ... from rextendr::document into devtools::document

[multimeric]

I've been hitting an issue where, when I run rextendr::document(), I get:

Error in getDLLRegisteredRoutines.DLLInfo(dll, addNames = FALSE) : 
  must specify DLL via a “DLLInfo” object. See getLoadedDLLs()

This issue is caused by roxygen, and has a long discussion here. The short solution is to simply use roxygenise(load = "source").

However, I can't use this load argument with rextendr::document. It would be nice if I could, for this reason. We could just forward all additional arguments to the underlying documentation function.

Sounds reasonable. Feel free to submit a PR.

Ah, actually this would require using roxygen::roxygenize() as the underlying function, which is a bit trickier because we would lose all the nice devtools info messages.

@multimeric, is it still a major problem? devtools::document() internally calls roxygen::roxygenize(), so in principle we can duplicate the logic of devtools::document() , but I am not a fan of this solution.

I will close this since rextendr::document() is designed to closely follow devtools::document().
