log_help.cc: Don't re-flow codeblocks

Move to a (single) `log_content_body()` instead of the dual `log_pass_str()` (nothing used the string-based indent arg), and pass the `ContentListing` directly; printing codeblocks verbatim (with indent).
Refactor (non-codeblock) line splitting slightly so that it can print up to and including 80 characters before the line break.
Add comments.
