[PATCH] Colored log on any ANSI capable terminal

[PATCH] Colored log on any ANSI capable terminal

[Pavel Roskin]

Hello!

setterm only works on Linux terminal.  It should be safe to use raw ANSI
sequences -they work on most terminals, including xterm.  Nobody forces
you to use the "-c" option to "git log" on those stone-age terminals
that neither support nor ignore ANSI color codes.

I'm aware of $'...' but it may not work in bash 1.x.
