darcs patch: Support an interrupt flag, and primitive... (and 4 more)

[Brian Rice]

I've turned this trick for boot.c into a patch and then immediately  
issued a rollback for it, along with an extended comment describing  
its purpose and how to bootstrap the previous patches, so that this  
can be more easily reproduced by others or in the future if need be.

I think I will use this kind of approach in the future to record  
bootstrapping issues, for archival / reproducibility purposes.
