[issue833] hg churn

[Jesse Glick]

New submission from Jesse Glick <jesse.glick at sun.com>:

There is a minor bug in hg churn affecting new (or almost) new repositories; a
division by zero is attempted in such cases. Easy to reproduce:

tmp$ mkdir hgtest-churn
tmp$ cd hgtest-churn
hgtest-churn$ hg init
hgtest-churn$ touch foo
hgtest-churn$ hg add
adding foo
hgtest-churn$ hg ci -m foo
hgtest-churn$ hg churn
** unknown exception encountered, details follow
** report bug details to http://www.selenic.com/mercurial/bts
** or mercurial at selenic.com
** Mercurial Distributed SCM (version 0.9.5)
