Git-Hooks

Changes for version 0.036 - 2013-01-19

Interface changes
- Internal hooks now shouldn't die directly when they detect a problem. Instead, they should invoke the new Git::More::error method to produce the error message and return a boolean value indicating if they have succeeded. This way they don't need to stop at the first error, but can detect many more and generate more information to the user.
  - In order to support old hooks, run_hooks checks their return values. If they return a boolean, they're treated as modern hooks. If they return undef (and $@ is empty, so that it wasn't an exception) they are considered to have succeeded.
New
- Git::Hooks::run_hooks only dies after having run every internal and external hooks and seeing that not every one of them succeeded. This way the user gets informed of every problem and not just the first one found.
- Add method Git::More::error to be used by plugins to produce consistent error and warning messages to the user.
- Add method Git::More::clean_cache to delete a cache entry. It may be used by hooks just before returning to Git::Hooks::run_hooks in order to get rid of any value kept in the SECTION's entry.
Fix
- CheckLog did not treat empty commit messages correctly.
