Huh? Presumably "just use soft-wrapping" only applies to long lines. It isn't banning you from using linebreaks before function definitions. The next section is about linebreaks! Earlier on, it talks about lining thing up with tabs! It can't be advising you to write entire programs on one line. But anyway, don't you have a code editor with a sidebar with function names, that you can click on to go to the definitions? Sounds like choosing to navigate via grep is the nature of the problem with grepability. And other search tools that aren't regex based can search for multi-line text. This isn't about plain text, it's about Vim. It's like saying "this farmer's field should be constructed differently because it isn't skateable".
