VignetteBuilder DECSRIPTION field split over lines is not recognized

[jackwasey]

I have a package DESCRIPTION which, after using desc package to reformat, contains:

VignetteBuilder:
    knitr

In this case, using

usethis:::use_description_field("VignetteBuilder", "knitr")

or, as I originally did:

use_vignette("Medical Twitter strategies used by other authors")

gives the error:

Error: VignetteBuilder has a different value in DESCRIPTION. Use overwrite = TRUE to overwrite.

Furthermore, the error message refers to an argument to usethis:::use_description_field which is not passed through by use_vignette and thus it is not possible to act on this by doing use_vignette("name", overwrite = TRUE)

@gaborcsardi there's no standard desc API for fields that are comma separated values, right? So this will require an issue in desc first.

[gaborcsardi]

@hadley yeah, but this is relatively simple, and there are not too many comma separated fields. So maybe usethis could just handle this?

[hadley]

Yeah, I can handle it too.
