[PATCH v2 1/2] docs: correct trailer `key_value_separator` description

[Brian Lyles <brianmlyles@gmail.com>]

The description for `key_value_separator` incorrectly states that this
separator is inserted between trailer lines, which appears likely to
have been incorrectly copied from `separator` when this option was
added.

Update the description to correctly indicate that it is a separator that
appears between the key and the value of each trailer.
