inheritParams sometimes doesn't inherit parameters #236
Description
For example, see this line:
https://github.com/hadley/devtools/blob/3f727a1313db1c06b2e832b4684ec10b31dc58b0/R/dev-help.r#L77
The corresponding Rd file doesn't show any of the inherited arguments:
https://github.com/hadley/devtools/blob/3f727a1313db1c06b2e832b4684ec10b31dc58b0/man/help.Rd#L11
This probably has something to do with the use of the operator, utils::?``.
