Based on the use cases I posted in my last email, I think all of them 
would either be ambivalent to the decision, or would prefer treating 
them as modifications.

Outside of those use cases, there's definitely some situations where 
treating them as modifications would annoy people used to the status 
quo. Log files and compiler-generated files spring to mind.

So if you add the option to treat mtime-only changes as modifications, I 
definitely don't think it should be the default option.  It's also 
probably safe to leave that option out until some squeeky wheels speak up.

I think it needs to be automatically resolved, but I don't think it 
matters how it's resolved. Obvious choices would be:

A) now()
B) the latest of the two times
C) delete the property

Merging necessarily modifies the local file, so no matter which 
resolution you pick, you'll get a new text-time the next time you commit.
