Default color for commit hash in git-log is unreadable on bright background, and can't be changed.

Hi folks.

I'm latest stable git (1.6.2) on a bright background terminal.

Unfortunately, the default text foreground color for the "commit
<HASH>" line of git-log is 3 - yellow. And yellow writing is not very
readable on bright background. Of course, I could customize color 3 at
the terminal letter to be darker, but that breaks everything else that
uses color 3 as a background highlight (vim, ack, etc.)

I've scoured the man pages, but haven't found any way to set the color
for that line in .gitconfig.

So, I suggest that this should be considered a bug. At the very least,
there should be an easy way to set that color for all us using a
bright background terminal - the default Gnome Terminal, the default
Terminal.app, and generally the default on many systems.

Is there any good solution for this that I missed?

Thanks,

Fynn
