I agree that we can assume editors can grok files with LF
end-of-line just fine and we would not need to do the reverse
conversion on checkout paths (e.g. "read-tree -u", "checkout-index").

Textual diff generation needs to learn the CRLF-to-LF conversion
in diff_populate_filespec(); this needs to be done even when the
caller wants size_only.

Oops.

Not so fast.  What's your plan for st_size?

Not me.
