I've finally found why the two machines behaved differently.  On the  
machine that did not detect diffs as language Diff, today I noted  
that the first line of the diff was actually a ruby warning that my ~/ 
bin directory was world writable.  I changed the permissions, and now  
the diffs do not have that warning as the first line, and they are  
automatically detected as language Diff.

I am left with one comment - if it is important that my ~/bin not be  
world writable, perhaps there is a better way to inform the user than  
hide a warning line at the top of a diff.  Given that this is the  
only time TextMate has warned me about this, I suspect that it is not  
considered a TextMate concern, and ruby is the culprit.  Perhaps this  
ruby warning should be caught, and not make it to the diffs.
