Re: [PATCH] crlf: Add test showing double warning on commit

Do we need to run diff_populate_filespec() twice when src==dst ?

Of course we do.

src and dst may have the same path, but are coming from different
places (src may be an indexed blob while dst may be a file in the
working tree).

If yes, we may need to introduce a flag besides
#define CHECK_SIZE_ONLY 1
#define CHECK_BINARY    2
to suppress the conversion warning ??

I do not think that belongs to diff_populate_filespec() at all.

Why should conversion routine give this warning when called by
diff_populate_filespec() in the first place?  Shouldn't it be silent
by default, and is allowed to talk _ONLY_ when we are attempting to
actually replace the data in the index, e.g. "git add" and "git
commit -a"?
