Re: [PATCH] find_unique_abbrev(): honor caller-supplied "len" better

But it is somewhat expensive to calculate "max current uniqueness", so
I would suggest ditching the whole notion of "how many extra numbers

Thanks; apparently our mails crossed...

I suspect that in a sane repository with set of reasonably packed objects,
we can cheaply get a rough estimate of the number of objects to about an
order of magnitude (e.g. "likely to have 10k to 100k objects"), and we
might able to come up with a way to automatically raise the default
length.
