Un-Line-Break is a lightweight plugin with a very specific purpose: Improved shortcode readability.
Normally, in the post editor, placing shortcodes on separate lines (like HTML formatting) results in extra line breaks in the rendered output, thanks to the WordPress auto-paragraph function (wpautop).
This plugin removes those extra line breaks from the rendered output so, in the post editor, you can place shortcodes on separate lines, thus making it easier to read and edit them.
It will not remove any double-spacing or <code></code> or <code> </code> tags that you have added.

Un-Line-Break

Remove unwanted line breaks from shortcode content.
