Well, I could have copied documentation from the header file into the commit
message

First, the unsorted file is bounded in size to make sure it never gets
large enough to really impact performance
Second, I'd ask you to look at the performance numbers (in patch #0)
before commenting on the performance.

I have indeed tried to follow the 80-chars-per-line rule. In softrefs.h
I fail to see a _single_ line exceeding 80 chars per line. In the other
files I believe the number of long lines is comparable to other files
in the git repo.
