Mark places that need blob munging later for CRLF conversion.
Here's a patch that I think we can merge right now. There may be other places that need this, but this at least points out the three places that read/write working tree files for git update-index, checkout and diff respectively. That should cover a lot of it [jc: git-apply uses an entirely different codepath both for reading and writing].
Some day we can actually implement it. In the meantime, this points out a place for people to start. We *can* even start with a really simple "we do CRLF conversion automatically, regardless of filename" kind of approach, that just look at the data (all three cases have the _full_ file data already in memory) and says "ok, this is text, so let's convert to/from DOS format directly".
THAT somebody can write in ten minutes, and it would already make git much nicer on a DOS/Windows platform, I suspect.
And it would be totally zero-cost if you just make it a config option (but please make it dynamic with the _default_ just being 0/1 depending on whether it's UNIX/Windows, just so that UNIX people can _test_ it easily).
