Currently, diff only ignores files that are considered binary by file_io.cc guess_binary. But the user might have other reasons to exclude a file (such as it's too large, or it has a format that some other tool handles much better). Rather than having to specify --exclude every time, setting the mtn:manual_merge attribute should have that effect, just as that attribute excludes the file from internal merging.

Steps to reproduce the problem:
-------------------------------

1. add a large (50 MB) text file 
2. run mtn diff; notice that it chokes 
3. add mtn:manual_merge to large file
4. run mtn diff

Expected result:
----------------
does not diff the manual_merge file, outputting a message about "has mtn:manual_merge attribute" instead.

Actual results:
---------------
still chokes (hangs, produces no output for a _very_ long time).


Output of `mtn version --full`:
-------------------------------
1.0
