be verbose if we're going to prompt

[kevinushey]

Since the output we display might be controlled by renv.verbose.

[aronatkins]

Should the documentation for any of the prompt arguments or the renv.verbose option discuss their interactions?

[kevinushey]

Hmm... we don't actually document the use of renv.verbose anywhere. Maybe it deserves a mention in a vignette?

[hadley]

Agree that it would be good to document this somewhere, but it's not clear where.

Suggested change

	renv_scope_verbose_if <- function(value) {
	if (value) {
	renv_scope_options(
	renv.verbose = value,
	scope = parent.frame()
	)
	}
	}
	renv_scope_verbose_if <- function(value, scope = parent.frame()) {
	if (value) {
	renv_scope_options(
	renv.verbose = TRUE,
	scope = scope
	)
	}
	}

value -> TRUE makes the logic a bit clearer IMO and I think it's good practice to always have a scope argument.
