Ah, I see.  I thought you were talking about the Index: and
separator lines.  Colorizing diff/patch part, you need to parse
the diff output with sed/awk/perl and annotate it anyway, and it
does not matter if you annotate within GIT_EXTERNAL_DIFF or
outside.  I agree with you that using GIT_EXTERNAL_DIFF
mechanism would not help you here.
