[PATCH 2/6] lib/string: Fix erroneous 'overflow' documentation
From: Tobin C. Harding
Date: Mon Feb 18 2019 - 18:24:21 EST
Current documentation uses 'overflow' to describe a situation where less
data is written to a buffer than buffer size not more. 'overflow' is
the wrong word here - since we don't typically say 'underflow' change
the whole sentence.
Fix erroneous 'overflow' documentation for under filled buffer.
