[PATCH v3 0/4] Colorize push errors

[Johannes Schindelin <johannes.schindelin@gmx.de>]

To help users discern large chunks of white text (when the push
succeeds) from large chunks of white text (when the push fails), let's
add some color to the latter.

The original contribution came in via Pull Request from the Git for
Windows project:

	https://github.com/git-for-windows/git/pull/1429

I almost forgot to submit v3. Guess it's a good thing I have a project
management system with tickets I can move through a story board...

Changes since v2:

- removed a bogus "squash! ..." from the commit message of 2/4

- removed the unnecessary here-doc from the test added in 4/4

- renamed color.advice.advice to color.advice.hint in 2/4 and 4/4


Johannes Schindelin (3):
  color: introduce support for colorizing stderr
  Add a test to verify that push errors are colorful
  Document the new color.* settings to colorize push errors/hints

Ryan Dammrose (1):
  push: colorize errors
