[PATCH v4 0/6] Documentation for common user misconceptions

This is v4 of a series improving the documentation to cover common user misconceptions.

I did opt to keep the big commit information section because I think it provides value when documenting the ordering of the variables. Otherwise, it becomes confusing to advanced users which options control what and in what order.

Changes from v3:
* Restructure docs around git-commit(1).
* Improve wording about templating as suggested by Peff.
* Document ordering between user.*, author.*, and committer.*.
* Document the environment variables more thoroughly.

Changes from v2:
* Move author and committer information to git-commit(1) where people
  will look for it.
* Move guidance on user.name format to git-commit(1) as well and mention
  a shortened form of the advice in the `user.name` description.
* Use a parenthetical to describe a "personal name" without contrasting
  it with a username.
* Offer a potential solution for people who want to ignore tracked
  files by recommending a templating mechanism.
* Be slightly more verbose about why memory is wasted with
  http.postBuffer.

Changes from v1:
* Remove parenthetical which was confusing.
* Add two more patches.
