mkhelp: simplify the generated hugehelp program

Browse Source 
Use a plain array and puts() every line, also allows us to provide the
strings without ending newlines.

- merge blank lines into the next one as a prefixed newline.
- turn eight consecutive spaces into a tab (since they can only be on the
  left side of text)
- the newly generated tool_hugehelp is 3K lines shorter and 50K smaller
- modifies the top logo layout a little by reducing the indent

Closes #13047
