patch, 4 partsDocumentation update (mainly for apply)

Here is my updated patch series based on Junio's feedback.

The first patch now also updates the description of -z for the log and diff* commands.

The second patch has better wording based on Junio's suggestion.

I have swapped patch 3 and 4 so that the "working tree" patch comes last, to make it easier to replace or drop.

Björn Gustavsson (4):
  Clarify and correct -z
  apply: apply works outside a repository
  apply: Format all options using back-quotes
  apply: Use the term "working tree" consistently
