merge: undocument checkunknown and checkignored configs for 3.7
We've discovered an issue with this flag during certain kinds of rebases. When:
(1) we're rebasing while currently on the destination commit, and
(2) an untracked or ignored file F is currently in the working copy, and
(3) the same file F is in a source commit, and
(4) F has different contents in the source commit,
then we'll try to merge the file rather than overwrite it.
An earlier patch I sent honored the options for these situations as well.
Unfortunately, rebases go through the same flow as the old, deprecated 'hg
merge --force'. We'd rather not make any changes to 'hg merge --force'
behavior, and there's no way from this point in the code to figure out whether
we're in 'hg rebase' or 'hg merge --force'.
Pierre-Yves David and I came up with the idea to split the 'force' flag up into
'force' for rebases, and 'forcemerge' for merge. Since this is a very
disruptive change and we're in freeze mode, simply undocument the options for
this release so that our hands aren't tied by BC concerns. We'll redocument
them in the next release.

'''histogram of changes to the repository
This command will display a histogram representing the number
of changed lines or revisions, grouped according to the given
template. The default template will group changes by author.
The --dateformat option may be used to group the results by
date instead.
Statistics are based on the number of changed lines, or
alternatively the number of matching revisions if the
--changesets option is specified.
Examples::
# display count of changed lines for every committer
hg churn -t "{author|email}"
# display daily activity graph
hg churn -f "%H" -s -c
# display activity of developers by month
hg churn -f "%Y-%m" -s -c
# display count of lines changed in every year
hg churn -f "%Y" -s
It is possible to map alternate email addresses to a main address
by providing a file using the following format::
<alias email> = <actual email>
Such a file may be specified with the --aliases option, otherwise
a .hgchurn file will be looked for in the working directory root.
Aliases will be split from the rightmost "=".
