[PATCH RFC 0/7] Bug fixes and preparation for example hook

[Jacob Keller]

I am currently working on a hook which can automatically detect which project a
patch applies to, if given proper index information in the patch diffs. The
following sequence of patches are the required changes to the core to make this
work, as well as a few bug fixes and general improvements.

The first patch just renames the email configuration variable in line with
request from Artem.

The second patch I am not sure which is better, allow default pcfg_path or not
allow default pcfg_branch. I think it's ok to force branch and path for each
project.

In line with how aiaiai-email-test-patchset works, change semantics for hooks
so that they shouldn't exit with non-zero unless they have an internal error.
In addition, we should call the hook slightly later in the file and add some
more verbose warnings.

Next, we begin a sequence of additional features, that my example hook I am
going to propose will be able to work.

First, the ability to specify a base commit, similar to how my old grep-log for
subject code did. However, I have a much more robust method for finding the
base commit in mind.

Next, add the ability for the hook to cancel patch testing, by adding a
boolean. I could go with a better name, but I couldn't think of one, so please
provide an idea if you have one.

Finally, explain best practice for hooks using non-standard configuration
variables. There really is nothing we can or should do to stop a hook author,
but it is good to warn about it.

I am hoping to finish testing against my idea for an example hook that can
automatically determine what project the patch applies to.
