Subject: [PATCH] Work around Mac's broken sed

sed on Mac is apparently incredibly broken and incapable of adding
newlines.  `printf 'x' | sed 's/x/\n/'` results in 'n' on Mac rather
than a newline.  GNU sed even in --posix mode does not agree with this
behavior.  None the less, we can work around it here.
