[PATCH 2/3] fast-export: rename --signed-tags='warn' to 'warn-verbatim'

[Luke Shumaker <lukeshu@lukeshu.com>]

From: Luke Shumaker <lukeshu@datawire.io>

But still keep --signed-tags=warn as an undocumented alias.  This name
is clearer as it has symmetry with warn-strip:

                   action              ->                   action
       +----------------------------+  ->       +----------------------------+
  msg? |      verbatim |      strip |  ->  msg? |      verbatim |      strip |
       |          warn | warn-strip |  ->       | warn-verbatim | warn-strip |
       +----------------------------+  ->       +----------------------------+
