shortlog: optimize out useless string list
If we are in "--summary" mode, then we do not care about the
actual list of subject onelines associated with each author.
We care only about the number. So rather than store a
string-list for each author full of "<none>", let's just
keep a count.
This drops my best-of-five for "git shortlog -ns HEAD" on
linux.git from:
real 0m5.194s
user 0m5.028s
sys 0m0.168s
to:
real 0m5.057s
user 0m4.916s
sys 0m0.144s
That's about 2.5%.
