Feedback on scaffolds

[jennybc]

Renviron exercise:

• List the usethis functions in rough order of usage. E.g. usethis::create_project() definitely comes before usethis::use_readme_md().
• Mention the use of Sys.getenv() to verify the existence and value of the new GITHUB_PAT env var.
• For you: anticipate the perennial "lack of newline at the end of file" problem. Which reminds me: Do we already have a place where we recommend certain settings that everyone should have in startup files and RStudio Global Options? That fits well into WTF and specifically your "system setup / startup" material. Like a health check for everyone.

Suggest you rename the scaffolds to indicate the .Renviron exercise vs. .Rprofile.
