Backwards compatibility with `crlf` attribute
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
These two sentences are confusing because the description of the text attribute sounds exactly the same as the description of the text=auto attribute: "Setting the text attribute on a path enables end-of-line normalization" "When text is set to "auto", the path is marked for automatic end-of-line conversion" Unless the reader is already familiar with the two variants, there's a high probability that they will think that "end-of-line normalization" is the same thing as "automatic end-of-line conversion". It's also not clear that the phrase "When the file has been committed with CRLF, no conversion is done" in the paragraph for text=auto does not apply equally to the bare text attribute which is described earlier. Moreover, it falsely implies that normalization is only suppressed if the file has been committed. In fact, running `git add` on a CRLF file, adding the text=auto attribute to the file, and running `git add` again does not do anything to the line endings either. On top of that, in several places the documentation for the eol attribute sounds like either it does not affect normalization on checkin or it forces normalization on checkin. It also sounds like setting eol (or setting a config variable) is required to turn on conversion on checkout, but the text attribute can turn on conversion on checkout by itself if eol is unspecified. Rephrase the documentation of text, text=auto, eol, eol=crlf, and eol=lf to be clear about how they are the same, how they are different, and in what cases conversion is performed.
