[Rd] missing news entry?

[Benjamin Tyner]

Hi,

Unless I am mistaken, this enhancement to gc():

------------------------------------------------------------------------
r73749 | luke | 2017-11-18 13:26:25 -0500 (Sat, 18 Nov 2017) | 2 lines

Added 'full' argument to gc() with default 'TRUE' for now.

------------------------------------------------------------------------

appears to be lacking an entry in doc/NEWS.Rd. Just FYI, in case there 
is capacity to add one.

Regards

Ben
