Merge branch 'jt/format-patch-base-info-above-sig'

gitster · gitster · commit e8f871a9cefb · 2016-09-21T15:15:27.000-07:00
"git format-patch --base=..." feature that was recently added
showed the base commit information after "-- " e-mail signature
line, which turned out to be inconvenient.  The base information
has been moved above the signature line.

* jt/format-patch-base-info-above-sig:
  format-patch: show base info before email signature
