Re: [question] retrieve some patches from another repository

This is inevitable, if 'x' and (say) 'b' corresponds to each other but has
textual changes due to different context.

You are probably running "format-patch a.. -- path/to/file.c".  Try giving
it the --full-diff option as well.  We've recently discussed to make it
the default for format-patch but the discussion thread petered out and
didn't reach conclusion.
