Oh, I know how to use sed&replace on a single line. What if deps tuple
spans over multiple line which is usually the case? I have an idea how
to do it in sed but awk is much simpler to approach this.

Or met the same argument and given up... ;-)

Already did that. At the beggining I wanted to use sponge from moreutils
but I assumed it's not desired to depend on some tool not in @system or
specific gawk implementation and version (which is not even stabilized
yet) just for eclass/ebuild internals. But apparently it's fine, so I
did that, as I've said in some other response.
