[PATCH v2 0/5] git-worktree documentation cleanups

[Eric Sunshine <sunshine@sunshineco.com>]

This is a re-roll of [1] which fixes some problems I ran across in the
git-worktree documentation while working on another worktree-related
topic.

This version adds some `linkgit:` invocations, typesets `HEAD` as
fixed-width, and covers a few additional places where backticks should
have been applied in place of other quotes, as suggested by Martin[2],
as well as a few more I noticed beyond those found by him. Although I
had planned on adding backticks around `HEAD` in a separate patch, I
ended up folding that change into patch 1 since there are relatively few
such instances, and since, upon reflection, such a change didn't seem to
warrant its own patch.

I omitted Taylor's Reviewed-by:[4] since the patches have changed since
he reviewed them, but he's welcome to give it again.

Eric Sunshine (5):
  git-worktree.txt: employ fixed-width typeface consistently
  git-worktree.txt: consistently use term "working tree"
  git-worktree.txt: fix minor grammatical issues
  git-worktree.txt: make start of new sentence more obvious
  git-wortkree.txt: link to man pages when citing other Git commands
