Is the last "Since ..." continuation of the above two, i.e. "with
the current code, the first one (unfortunately) means the same as
the second one, BECAUSE ..."? If so, s/Since/since/ (I needed to
read it twice to guess that is probably what you meant).
The above is a very good justification of the entire series,
illustrating why this is worth doing.

s/to obey/obey/ (make X do Y, not make X to do Y); I'd probably
further do 's/obey/honor/' or even 's/obey/work better with/'

It is kind of disappointing that the none of the above block of
configuration examples does not quite say what the reader really
wants to know directly. I am guessing that the point is
now text=auto does autodetection even when eol=crlf is
specified, and files that are declared to be non-text will not
get clobbered with eol=crlf conversion
right? If that is the case, replacing everything below "In other
words" with these three lines would make the text much easier to
grok, I would think.

This is not a new problem but the last sentence and a half look
bad. Telling readers "X is not guaranteed to happen" is not all
that useful--telling them what happens is. Also the use of colon
there is probably ungrammatical.
Set to true if you want to have CRLF line endings in your
working directory and LF line endings in the repository.
Text files that contain CRLF in the repository will not get
their end-of-line converted.
perhaps?

Are these bits in a word? If not where did 3 go?

Hmph, do we want UNDEFINED case to return EOL_CRLF here?
