BUG: %+ format placeholder and colors

[Raphael Bauer <raphael@pdev.de>]

Hello,

I am not familiar with using mailing list for bug tracking. I already 
reported this bug, but got no answer, so I wanted to mention it again.

* What did you do before the bug happened? (Steps to reproduce your issue)
git log --pretty=format:'%h%Cred%+d test' --graph

This also happens with a PAGER=cat environment, just to preclude this is 
related to the pager.

* What did you expect to happen? (Expected behavior)
A graph listing of commit hashes and, if ref names for this commit 
exist, a second line.
This line should be colored in red and contain the ref names as well as 
the string 'test'.
In the case of no refs, the string 'test' should appear in line with the 
commit hash, also in red.

* What happened instead? (Actual behavior)
In case of ref names / a second line, the color is missing completely.
The colors work correctly for the single line case (when no ref names 
are available).

* What's different between what you expected and what actually happened?
The %+d placeholder inserts newlines if the string is non-empty, but in 
doing so, resets any coloring information.
This is demonstrated by the string 'test' which should always show in 
red, but does so only if %+d is not expanded.
This makes it currently impossible to color anything with the %+ 
placeholder.


If this is already tracked, I apologize.
