OS.Grep File: Moved 'new in' line to last in doc.
OS.Grep File: Moved 'new in' line to last in doc.

Update issue 1655
Status: Started
Get File and Grep File look good. Moved 'new in' line in the latter to last in doc and did some general test data clean-up in previous commit.

Noticed there is also Log File keyword that should get `encoding_errors` too.
