The -s option allows skipping patches at the top of the branch. Sometimes
there are commits at the bottom that need to be skipped. At present it is
necessary to count the number of commits and then use -c to tell patman
how many to process.
Add a -e option to easily skip a number of commits at the bottom of the
branch.

To make testing easier, move the code out from main into a separate
'control' module and split it into four parts: setup, preparing patches,
checking patches and emailing patches.
Add comments and fix a few code-style issues while we are here.
