Yes, that is better. Let me know if you want me to resend.

I wondered what "this format" was, and had to read the patch with
"show -U60" to realize that this is about "--pretty=<format>".
Perhaps the introductory text of the first paratraph in the section
is not clear enough that not just --pretty=raw but --pretty=anything
is about how the commit object is shown and has nothing to do with
how patches are shown, and that is why this new text is necessary?

I would say no, since other formats do not have this "raw log format" Vs
"raw diff format" confusion.

I looked for a way to have this disclaimer under 'PRETTY FORMATS'
outside the 'raw' subsection, but I found no place where this would not
be weird like "oh, BTW, this section has nothing to do with patches"
when the user did not have any notion of patch in mind.

The confusion was rather serious here since 1) looking for the string
"raw format" was directly pointing to the paragraph I patched, and one
may do this search looking for information on raw diff format, and 2)
the text was explicitly saying that all sha1s were unabreviated while
--format=raw --raw still shows abreviated commits. Neither of the
confusion are problematic with other formats.
