contacts: reduce git-blame invocations
git-contacts invokes git-blame once for each patch hunk it encounters.
No attempt is made to consolidate invocations for multiple hunks
referencing the same file at the same revision. This can become
expensive quickly.
Reduce the number of git-blame invocations by taking advantage of the
ability to specify multiple -L ranges for a single invocation.
Without this patch, on a randomly chosen range of commits:
% time git-contacts 25fba78d36be6297^..23c339c0f262aad2 >/dev/null
real 0m6.142s
user 0m5.429s
sys 0m0.356s
With this patch:
% time git-contacts 25fba78d36be6297^..23c339c0f262aad2 >/dev/null
real 0m2.285s
user 0m2.093s
