bat's gitllog language-colorization is slightly confused by git log --decorate=[short|full] output

[hivehand]

Describe the bug you encountered:

If I pipe the output of git log through bat as follows, each commit line is properly colored:

git log | bat  

If, however, I tell git to decorate the log using the --decorate flag, any commit lines sporting a ref appear in plain white, with no coloring.

git log --decorate=short | bat

What did you expect to happen instead?

I expected the commit text, and the hash, to be colored as they are for ref-free commits; I would like for the "HEAD", "master", and origin refs to be colored as they are in regular git log output.

How did you install bat?

Via Homebrrew.

P.S.

Incidentally, thanks! I absolutely love, and am grateful for, bat — both because it deals gracefully with nearly all of the situations I've thrown at it, and because its atomic-binary nature means I can easily copy it to systems I don't have root access to. Cheers!
