How to insert paragraph separators

[elef]

Hi all, I'm trying to find a way to insert separators into e-books created with the converter (from txt files, mostly into .mobi format).
I have found one way of doing it: Add a line that only contains this:
----------
This is converted into a continuous horizontal line, which is fine for me. But there is a lot of wasted empty space after the line.
Like this:




I would like to pack text more tightly in order to get more text on the screen. So, is there any way to generate a similar horizontal line or other decent-looking separator element that is not followed by what is basically a blank line?

Those look similar to what Calibre calls soft scene breaks, A special Paragraph (found on the Conversion: Heuristic Process: tab of the conversion starting screen)

IMHO Paragraph Top (and bottom) Margins are the way to adjust the whitespace

To code a ( device robust) 74% width HR, 1/2em whitespace (in book editor)

usage: <hr class="hr74" />

Stylesheet: .hr74 {display block; margin: 0.5em 12%; text-align: center}

Thanks.
Right now all I do is run this in the console:
ebook-convert.exe "inputfile.txt" "outputfile.mobi" [+author, title, language]
Ideally, I need a solution that involves just adding some command line options.

I had a quick look at the documentation at http://manual.calibre-ebook.com/cli/ebook-convert.html
The --remove-paragraph-spacing option seems to do the trick. I don't have my kindle at hand right now, but I think it will look OK. Maybe I will use --remove-paragraph-spacing-indent-size 0 to get rid of indents as well. BTW if I decide I want some spacing, just less than the original, am I out of luck? Because I can't see a command line option to specify paragraph spacing, just to eliminate it.

Update: --remove-paragraph-spacing --remove-paragraph-spacing-indent-size -1 gives exactly the output I was looking for.
