darcs-fast-export merges the patch name and the long description together

When reimporting the result into git you'll see that there's no separation between the lines, in other words

    git log --oneline

will show the whole changelog (well, up to the first empty line) as a single line.

I did not (yet) tried the darcs-fast-import script, but I guess it should perform the inverse fix, otherwise there will be a spurious (even though innocuous) empty line between the patch name and its long description.
