patchbomb: includes series information in the header
We includes information about the series being patch bombed in all email. Two
new headers are added:
* X-Mercurial-Series-Index: index of the patches in the series (starts at 1)
* X-Mercurial-Series-Total: The total number of patches in the series
This information is available in the email subject line, but having them
formalized in the header will helps automated tools to process patches send with
modern mercurial.
pager: add attend-<command> option
This lets users override attend settings locally on a command
granularity.
