Patch to fall-back to git's algorithm if terminfo is unavailable
Curretnly llvm needs to be build with terminfo support in order for colors to
be enabled automatically in clang diagnostics.
ncurses/terminfo is a bit of a heavy dependency if all you want is to determine
color support as that is pretty much universal for today's *nix terminal
emulators. This requirement for terminfo was introduced in r187874.
There has been some discussion on this on the mailing lis:
<a href="https://groups.google.com/forum/#!topic/llvm-dev/MqpXVMy6OrM">https://groups.google.com/forum/#!topic/llvm-dev/MqpXVMy6OrM</a>
A suggestion from there that I'd like to see implemented is falling back to the
much simpler algorithm used by git to determine if the terminal supports color
codes:
