Does it possible to learn bzr to process pdf files as binary?

Hi,

There's no option at the moment to change this. The file looks like text, it is printable, so bzr diffs it that way.

I can think of a couple of things we could do to improve this; maybe you can suggest more

1- a configurable list of file patterns (maybe as rules) to be treated as text or treated as binary, regardless of the contents of the files

2- a better heuristic that determines that this file is not really human-readable

I think diff is hookable at the core; a plugin could do better.

I think it is a good way to solve this problem to allow users to configure their preferences via some file
