[PATCH 0/3] doc: unify config info on some cmds

These three patches attempt to remove duplication between some config/*.txt and git-*.txt files, to facilitate maintenance and fix any divergences.

This series targets the most straightforward conversions, but there are also other commands whose config documentation could possibly be unified (maybe #leftoverbits):

- git-log.txt and config/log.txt have some duplications, but with
  different wordings, which could probably be standardized.

- git-send-email.txt has some config definitions "inlined" with the
  descriptions about the CLI options (e.g. sendemail.xmailer). Not sure
  if it is worth unifying the configs in this case.

- Some cmds like format-patch, status, and branch have some config variables
  defined at config/*, but not at git-*.txt. Maybe the latter could
  mention something like "See the full list of available <cmd>.*
  configuration variables at git-config(1)."
