Junio C Hamano fba9654364 Merge branch 'jk/trailer-fixes' 
"git interpret-trailers" and its underlying machinery had a buggy
code that attempted to ignore patch text after commit log message,
which triggered in various codepaths that will always get the log
message alone and never get such an input.

* jk/trailer-fixes:
  append_signoff: use size_t for string offsets
  sequencer: ignore "---" divider when parsing trailers
  pretty, ref-filter: format %(trailers) with no_divider option
  interpret-trailers: allow suppressing "---" divider
  interpret-trailers: tighten check for "---" patch boundary
  trailer: pass process_trailer_opts to trailer_info_get()
  trailer: use size_t for iterating trailer list
  trailer: use size_t for string offsets
