I think up to your 3/4 is reasonable, but this is not enough for POSIX
conformance (it is Ok if it is just aiming to fix "Solaris quirk"). POSIX
sed is only required to work on text files, but .git/MERGE_RR is not a
text file (it is a sequence of NUL terminated records).
I think something like this may work better. Can somebody test?
