Print eight spaces when no leading commit is being printed.
I.e. on all rows of a commit-block, but the first.  This fixes
alignment in the destination buffer when blame data lines
are cut and pasted.

Also, now all rows have title.

Its visuals might be Ok (I haven't had chance to try it), but I
am a bit worried about the output size bloat.  What kind of
bloat factor are we talking about with this patch?

 - compared to the ancient original, which used to have commit-8
   on all lines, title * N lines for a file that is N lines
   long.  A title ("$author, $date") is about say 30 bytes or so
   so for a file that is on average 25 bytes per line (this is
   from "wc *.c" in git.git repository ) we are now spewing out
   roughly twice the bytes back to the browser (25+8 vs 25+8+30)

 - compared to "only first in the block" version, assuming an
   average group size is 10 lines or so (this is a totally made
   up number) we are adding 72 extra bytes per 10 lines for
   commit-8 on top of the title bloat which would be 270 bytes
   per 10 lines.  Again assuming 25-byte per line average, that
   is 250+8+30 vs 250+80+300 per 10 lines.  Again, roughly
   twice.

I am not sure what the numbers of the chunked one I just
reverted from "next" compared to the original.  For the same
group size assumption, it added 8 bytes for commit-8 and 30
bytes for title per the N lines, but we are assuming 10-line
blocks, so 38 byte overhead per 10 lines, which is 250+80 vs
250+38, so it might have been actually slimmer than the
original.

```

Yes, I agree with you.  That patch adds bloat.  I agree with
you, we can print the "title=" only for the leading commit-8,
as we currently do, and dispense with 8 SP.  In effect this
patch 2/2 can be dropped.

Thanks,
   Luben
