dev-lang/R: new revision that leaves more docs uncompressed.

The R interactive shell encourages users to read several documentation
files using functions like contributors() and RShowDoc() that rely on
the files being installed with their god-given names. This new revision
tries to fix a few of the more common ones with docompress -x.
