Well, as I say it looks to me like the facility was there in the
lowest level.  Since you don't understand what I'm saying, I should
look more closely and see if anything needs to be said at all.

Mostly people have been sending patches, that's why I noticed.

Unfortunately, the automatic commit notices suck as documentation.
First, there's no provision for discussing motivation and other
background to the patch, the stuff that generally doesn't belong in
ChangeLogs.  Second, they send the wrong patch any time Mercurial
merges, ie, in any case where it is an improvement over CVS. :-(
Specifically, it looks like the patch is undoing other people's work.

Don't worry about changing Patcher's docs.  I'll just use them as a
club to get Mike to fix the commit 'bot.

Probably because only Aidan offends in every single ChangeLog.

I wish you'd submit those as separate patches, though.
