Re: [PATCH] describe-doc: clarify default length of abbreviation

The explanation was mostly copied from the 2.11.0 release notes,
but mentioning the birtday paradox is unnecessary. I suggest
changing this sentence to: "The length of the abbreviation scales
as the repository grows using the approximate number of objects in
the repository, and by default the minimum length is 7."

Heh.  In my priate review, I said that I very much liked the way the
new description was phrased with "a bit of math around the birthday
paradox".  Now I know why I liked that phrasing---it turns out to be
my own ;-)

I don't mind with or without mention of the birthday math.  Thanks
for working on this.
