is then renamed to `.RData`.

`.RDataTmp` should be added to `.gitignore` since it will only exist
while a save operation is in progress or something failed on save.

Conflicts with JetBrains.gitignore. Some files in this directory should be checked in.

Not sure about *.sln.iml, so I'm leaving that. The JetBrains.gitignore file contains commented-out IML stuff with instructions on when to uncomment.

With Go 1.18, support for Go workspaces will land.
Go workspaces are configured in `go.work`, which
contains paths to local development versions of
modules and therefore is not expected to be
commited.
