Merge branch 'rr/for-each-ref-decoration'
Add a few formatting directives to "git for-each-ref --format=...", to paint them in color, etc. * rr/for-each-ref-decoration: for-each-ref: avoid color leakage for-each-ref: introduce %(color:...) for color for-each-ref: introduce %(upstream:track[short]) for-each-ref: introduce %(HEAD) asterisk marker t6300 (for-each-ref): don't hardcode SHA-1 hexes t6300 (for-each-ref): clearly demarcate setup

|

upstream::
|

The name of a local ref which can be considered ``upstream''
|
||||
from the displayed ref. Respects `:short` in the same way as
|
||||
`refname` above.
|

`refname` above. Additionally respects `:track` to show

"[ahead N, behind M]" and `:trackshort` to show the terse
|
||||
version: ">" (ahead), "<" (behind), "<>" (ahead and behind),
|

or "=" (in sync). Has no effect if the ref does not have

tracking information associated with it.

HEAD::

'*' if HEAD matches current ref (the checked out branch), ' '

otherwise.

Change output color. Followed by `:<colorname>`, where names

are described in `color.branch.*`.
