Merge branch 'pb/commit-verbose-config'

"git commit" learned to pay attention to "commit.verbose"
configuration variable and act as if "--verbose" option was
given from the command line.

  commit: add a commit.verbose config variable
  t7507-commit-verbose: improve test coverage by testing number of diffs
  parse-options.c: make OPTION_COUNTUP respect "unspecified" values

  test-parse-options: print quiet as integer
