Question about merge changeset emails

[Greg Lindahl]

My guys like to read through checkin emails. The following example
shows where 2 changesets get emailed out at once ... which isn't
helpful, as they want to ignore the merge changeset, which contains
only things that they've already seen (assuming no collision, which is
the case.)

How can I convince Mercurial to do something more useful like sending
2 separate emails in this case? Or suppressing the merge diff?

hgk gets this case right, it shows an empty diff for the merge
changeset.

And while I'm at it, is there any way to fix the details line to work
with hgwebdir.cgi without specifying an entire template?
