[PATCH v3] add configuration variable for --autosquash option of interactive rebase

[Heiko Voigt <hvoigt@hvoigt.net>]

If you use this feature regularly you can now enable it by default. In
case the user wants to override this config on the commandline
--no-autosquash can be used to force disabling.

No I did not see the exact use case because you could simply not prefix
you commits with 'fixup!' or 'squash!' and if your project regularly
uses those on commits you probably would like to configure different
prefixes.

On the other hand I think it is a good convention to always provide a
--no-... option for things you can enable in the config and it does not
hurt to do so. So here is a new patch implementing this. I also fixed
some places with missing && in the testcases I implemented.
