I think the point of the original is that you do not _need_ to quote
unless you have those two characters. IOW, you can do:
M 100644 :1 file \with \backslashes
and it will stay in the "literal to the end of line" code path because
the path does not begin with a double-quote. It is only when you trigger
the "shell-style quoting" code path is in effect that you must then
follow the rules of that quoting (which includes escaping backslashes).
So technically, your modification to the beginning of the sentence is
not correct.
That being said, I think what you have written is more helpful to an end
user. There is no harm in quoting when we do not have to, as fast-import
implementations must know how to unquote anyway (and we over-quote in
fast-export in this case). And while the example above does work (and
was always designed to), it is sort of an unintuitive area that I would
not be surprised to see other fast-import implementations get wrong. As
a writer of a stream, it probably pays to be defensive and err on the
side of quoting more.
As for the text itself, a few minor punctuation suggestions:

^
missing comma as list delimiter

^
missing comma in if/then clause
This one was in the original as well, but it makes it harder to read and
is worth fixing.

Should the parenthetical be in parentheses (or a separate sentence)?
