Dots in rename (r-lib#2038)

* Check uncommitted before renaming files.

Fixes r-lib#1969.

After digging into this a little, I think making sure everything is committed is enough. use_r() won't create a file with a `.` in it, so, unless you want to let this snowball, I think the check is enough.

* Only remove `.R` extensions from old/new.

* Don't use shorthand for function definition.

* Use older anonymous function syntax in more places
