explicit patch submission instructions

[shannonpileggi]

Recently at R Dev Day PLUS, Martin commented on how to submit the "perfect" patch. I see a related section in 7.4.1 & 7.6, but I don't think it as explicitly goes through all the steps regarding the attachment and such??

Appending .diff to the end of the [r-svn PR] URL automatically provides something you save from your browser as plain text file, named, e.g., toTitleCase_PR-18674.diff and then in R's bugzilla, you'd typically use the Add an Attachment option to add that *.diff file as attachment:

• on the new Create New Attachment web page, add a Brief Decription ,
• also click the Content Type: patch box, and then
• add comments (often prose text) below rather than in the original bugzilla page for the PR.
• press Submit This will give you a perfect bugzilla submission, with only one e-mail to all of R-core plus PR author and more listeners.

I think this is very useful and it would be great to add it to the book to annotate what was previously shared on individual cases. Perhaps @SaranjeetKaur who originally wrote the section can provide more feedback (or add it to the book).

Thanks for the tag @llrs and I agree with you that it would be great to add this to the dev guide.

@shannonpileggi - would you like to open a PR about the same?

Sure, will do! Thanks for the feedback!
