[PATCH v2 0/7] Fix leak of color/attributes in "git log --decorate"

In "git log --decorate", you would see the commit header like this:

    commit ... (HEAD, jc/decorate-leaky-separator-color)

where "commit ... (" is painted in color.diff.commit, "HEAD" in
color.decorate.head, ", " in color.diff.commit, the branch name in
color.decorate.branch and then closing ")" in color.diff.commit.

However, setting color.decorate.head to normal does not paint "HEAD"
in the "normal" color you have for your terminal.  It just uses the
same color it used to paint the "(", i.e. color.diff.commit.

Fixing this was a simple one-liner; the code forgot to reset the
terminal attributes before moving on to the next item.

It however turns out that the existing documentation was rather
messy and I ended up doing some preparatory clean-up on the
documentation around how configuration variables are explained
before updating the documentation to clarify that 'normal' ought to
work (in other words, the colors and attributes are not cumulative).

I am reasonably happy with the result, and I can go with or without
[6/7].

Junio C Hamano (7):
  Documentation/config.txt: avoid unnecessary negation
  Documentation/config.txt: explain multi-valued variables once
  Documentation/config.txt: describe the structure first and then meaning
  Documentation/config.txt: have a separate "Values" section
  Documentation/config.txt: describe 'color' value type in the "Values" section
  Documentation/config.txt: simplify boolean description in the syntax section
  log --decorate: do not leak "commit" color into the next item
