[racket-dev] "warning: CRLF will be replaced by LF in {src/worksp/README src/worksp/gracket/gracket.rc src/worksp/racket/racket.rc}" ?

Preface: I'm sorry if this is a really basic question, but I'm new to
this Git workflow, so I'm cautious because I don't want to cause a
nuisance with some future pull request.

I just did a `git fetch` of the upstream PLT master, then a `git
merge` into my master.
