Should have been changed from what to what?  And instead it was
changed to which other logic?  What is the difference between the
ideal this change tries to bring in and what c4805393 did?

s/will not/& be/;

It is unclear what this sentence wants to say.  The user may overwrite
the file with random contents and commit it, too.  So what?

What is missing from this statement is what problem is being worked
around.  Do you mean: "Because Git does not normalize once CRLF is
in the index, if the user wants to have a normalized content in the
repository to correct that mistake, the user needs to do dos2unix to
fix it and commit the fixed result"?

These two paragraphs are all "what I did to solve X", but what X is
is not very clear.

Missing sign-off.
