[PATCH] git add -e: Explicitly specify that patch should have no color

After this commit:
    4c7f1819b3c142ace98269a556bc929c80e7c9fd make color.ui default to 'auto'
the patch file for 'git add -e' receives all the color codes.  This is because
diffopt.use_color defaults to -1, which causes want_color to now return 'auto'.

By explicitly setting use_color to 0, we can ensure the diff output has no
color codes in it.
