[PATCH 2/6] lib/string: Fix erroneous 'overflow' documentation

[Tobin C. Harding]

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.
