Sure make sense. I suppose we should be consistant too and use $BACKPORT_DIR.

OK :)

I think I went trigger happy since the bk_src_line should have picked
up on the fact that backports directory prefix would already have been
used. I'll re-test and remove not needed thing and try to consolidate
the regexp.

What I meant by this was more of the things that could go into a Kconfig
which we perhaps are not parsing yet which might depend on a path, so
its not clear to me what regexp to use. Right now it will just leave
the lines intact and I guess that's fine for now.
